Outcomes
MacSync's climate readings are a trigger, not just a record — alerts, compliance logs, and HVAC decisions all act on them in real time, over the Wi-Fi network you already run.
Prevent Spoilage & Stock Loss
Deviation alerts reach your team the moment a cold room, chiller, or storage zone drifts out of range — before perishables, pharma stock, or materials are at risk.
Automate Compliance Records
Continuous, timestamped temperature and humidity logs replace manual clipboard rounds — audit-ready history for HACCP, pharma, and quality programs.
Alert Before It Becomes Downtime
Threshold-based event uplinks flag hotspots and humidity drift in server rooms, panels, and machine rooms while there is still time to act.
Optimize HVAC & Energy Use
Room-level climate data shows where heating, cooling, and dehumidification are overshooting — facilities teams cut energy spend without sacrificing conditions.
How it works
How Does the Wi-Fi Temperature & Humidity Sensor Work?
Step 1 of 5
Mount it where it matters
Wall or pole mount in minutes — no wiring, no gateway to install. Choose the internal sensor or the external probe for freezers and chambers.
Join your Wi-Fi with Maya
Pair over Bluetooth with the Maya app, hand the sensor your Wi-Fi credentials — 2.4 or 5 GHz, and set sampling intervals and alert thresholds — no laptop, no code.
It samples the climate continuously
Factory-calibrated sensing reads temperature and humidity on your schedule, from every minute to once a day, sipping microamps in between.
Readings ride your existing network
Data flows over your Wi-Fi to MQTT, HTTPS, or your private cloud — and if the network drops, 30,000 records buffer safely on-board.
Live climate data, anywhere
Dashboards, instant alerts, and audit-ready history — from a single cold room to every site you run.
In plain terms
What Is a Wi-Fi Temperature and Humidity Sensor?
The short answer
A WiFi temperature and humidity sensor is a battery-operated device that measures the temperature and relative humidity of a space and sends those readings to the cloud over an ordinary Wi-Fi network — with no gateway, hub, or receiver in between. Because it joins the Wi-Fi you already run, a site can be monitored using infrastructure that is already installed and already maintained.

MacSync Wi-Fi TH Sensor
The MacSync Wi-Fi TH Sensor is the industrial version of that idea: factory calibrated, rated IP65 and working from −40 °C to +80 °C. That is what separates it from the consumer plug-in monitors sold for homes and offices.
Temperature from −30 °C to +70 °C and relative humidity from 0 to 100%, sampled on an interval you set from 1 minute to 24 hours.
Directly to your existing 2.4 GHz or 5 GHz Wi-Fi network — no gateway, hub, or proprietary receiver to buy or maintain.
To MQTT brokers, HTTPS endpoints, or your own private cloud, so readings land in the dashboard or system you already use.
It doubles as a WiFi temperature data logger: 30,000 readings are stored in on-board flash, so a network outage or router reboot never leaves a gap in the record.
An industrial 19 Ah Li-SOCl₂ battery, estimated at about a year at 5-minute uploads and close to 7 years at hourly uploads, or 9–36 V DC for permanently powered installations.
Used in cold chain and pharma storage, warehouses, server rooms, and any facility that needs audit-ready climate records without new cabling.

Choosing a technology
Wi-Fi vs LoRaWAN vs Bluetooth for Temperature Monitoring
Macnman builds temperature and humidity sensors on all three technologies, so this comparison is about picking the right one for your site — not about selling you a particular radio.
| Criterion | Wi-Fi | LoRaWAN | Bluetooth (BLE) |
|---|---|---|---|
| Extra infrastructure | None — uses your existing Wi-Fi | A LoRaWAN gateway per site | A phone or hub in range |
| Typical range | Your Wi-Fi coverage, indoors | Kilometres, through walls and racking | 5–30 m, line of sight |
| Battery life | About 1 year @ 5-minute uploads, 6.8 years hourly | About 2 years @ 5-minute uplinks, 7+ years hourly | Months to a year, varies widely |
| Best for | Sites with good Wi-Fi and no appetite for new hardware | Large sites, remote assets, hundreds of sensors | Spot checks and short-range local logging |
| Sensors per network | Limited by your access points | 2,000+ per gateway | A handful per hub |
| Data path | MQTT / HTTPS to your cloud | Any LoRaWAN network server, then your cloud | Phone app, then manual upload |
| Offline safety | 30,000 readings buffered on-board | 30,000 readings buffered on-board | Depends on the device |
Ranges and battery figures are for Macnman sensors in typical deployments; real-world results vary with building materials, access-point placement, and reporting interval.
Reporting modes
Three Reporting Modes for Every Monitoring Strategy
The sensor samples and reports on a fixed schedule you set in the Maya app — anywhere from every minute to once a day. Predictable data, predictable battery life.
Note: Longer intervals extend battery life; compliance logging typically runs at 5–15 minutes.
Define temperature and humidity thresholds, and the sensor pushes an immediate uplink the moment a reading crosses them — your team hears about an excursion in seconds, not at the next scheduled report. Note: Threshold alerts work alongside either of the other modes.
Steady periodic records for your audit trail, plus instant event uplinks when conditions drift — the configuration most cold chain and pharma deployments run. Note: Sampling continues between uplinks, and 30,000 records buffer on-board through outages.
Cloud & LNS
Open Connectivity with Universal Cloud Compatibility
Streams to MQTT, HTTPS & Private Clouds — No Vendor Lock-In
MacSync Wi-Fi TH sensors publish readings over your existing network to MQTT brokers, HTTPS endpoints, or your private cloud — encrypted end to end, with no gateway hardware and no vendor lock-in.

FAQ
Frequently asked questions
No. The MacSync Wi-Fi TH sensor connects directly to your existing Wi-Fi network — 2.4 or 5 GHz — there is no hub, gateway, or base station to buy, install, or maintain. If your site has Wi-Fi coverage, you have everything you need.
Yes. The MacSync Wi-Fi TH sensor is dual-band — it connects to both 2.4 GHz and 5 GHz Wi-Fi networks, so it works on modern mesh systems, enterprise access points, and 5 GHz-only networks where single-band sensors fail.
Nothing is lost. Built-in flash memory stores 30,000 records on the sensor itself, so it keeps logging through router reboots, network outages, and maintenance windows — your temperature and humidity history stays safe on the device.
Yes — it is a wireless data logger and a live sensor in one. Readings are written to 30,000 records of on-board flash and streamed over Wi-Fi at the same time, so you get real-time dashboards plus a complete local history that survives network outages. Logging intervals are configurable from 1 minute to 24 hours.
It depends on how often it connects. On its industrial 19 Ah Li-SOCl₂ battery, the Macnman Wi-Fi battery life calculator estimates about 1 year at 5-minute uploads, 2.6 years at 15-minute uploads and 6.8 years at hourly uploads with DHCP and TLS. You set the interval from 1 minute to 24 hours in the Maya app, and a 9–36 V DC variant is available for continuously powered installations.
It is factory calibrated to ±0.3 °C between 0 °C and +70 °C (±0.6 °C below zero) and ±3% RH across the 10–90% humidity range — accurate enough for pharma, cold chain, and compliance-grade monitoring out of the box.
Yes. The sensor operates from −40 °C to +80 °C, and the external-probe variant lets the transmitter stay outside while the probe measures inside freezers, chambers, and enclosures — ideal for cold rooms and vaccine storage.
Yes. The glass-filled nylon enclosure is IP65 rated as standard, with an IP67 optional variant, and its thermal isolation keeps readings stable through rain, dust, heat, and freezing conditions.
Pair with the free Macnman Maya app over Bluetooth: connect the sensor to your Wi-Fi, set sampling intervals, choose periodic, event-based, or hybrid reporting, and define temperature and humidity thresholds. Cross one and the sensor sends an immediate excursion alert — no laptop required.
It streams readings to MQTT brokers, HTTPS endpoints, and private cloud platforms over your existing network — on WPA2 or WPA3 secured Wi-Fi, encrypted end to end, with no vendor lock-in and no gateway hardware in between.
Yes. Continuous data logging with configurable intervals produces audit-ready temperature and humidity history, and every temperature excursion is timestamped — the record-keeping pharma storage, food safety (HACCP), and cold chain compliance programs require.
Choose Wi-Fi when your sites already have good Wi-Fi coverage and you want zero new infrastructure. Choose LoRaWAN for very large sites, deep freezers at long distances, or hundreds of sensors on one gateway. Macnman builds both, on the same calibrated sensing platform, so you can mix them per site.
