A WiFi sensor connects directly to your local WiFi network — no proprietary hub, bridge or gateway required — and sends live readings to COMET Cloud, a browser or an app, with email/SMS alerts if a value goes out of range. Because there’s no data logger to retrieve, you get continuous, real-time visibility from anywhere.
Our COMET WiFi sensor range measures temperature, relative humidity, CO2 and barometric pressure — as ambient units, remote-probe thermometers, 4-channel probe sensors and combined T+RH+CO2+pressure models — built for warehouses, labs, server rooms, cold storage, schools and production facilities where accuracy, calibration and reliability matter, not a $20 home hygrometer.

The sensor has no significant onboard storage of its own, so the current live reading is always free to check — on the sensor’s own display, its local web page, or an app on the same network, no account needed. To keep a logged history, see trend graphs and multi-site dashboards, and get email/SMS alerts from anywhere, you need an active COMET Cloud subscription — every sensor includes a 3-month free trial, then it renews at a low annual rate. Prefer not to subscribe long-term? The sensor’s JSON, XML, Modbus TCP and SNMP outputs can feed your own BMS/SCADA or database for continuous logging instead.
Choose by parameter (T, RH, CO2, pressure), probe configuration (integrated, single or 4-channel external Pt1000) and channel count. We stock the COMET WiFi family — W0710/W0711/W0741 temperature, W3710/W3711/W3721/W3745 temperature & humidity, W5714 CO2, W4710/W7710 combined — with local stock, NATA calibration and support across Australia.
Need on-device data storage instead of continuous streaming? See our Wireless Data Loggers. Prefer PoE or mains-powered Ethernet? See those pages.
No. COMET WiFi sensors connect directly to your existing WiFi router or access point — there's no proprietary hub, bridge or gateway to buy or maintain, unlike many consumer smart-home sensors.
The current live reading is always free to check — on the sensor's display, its local web page, or an app on the same network, no account needed. To keep a logged history, view trend graphs and dashboards, and get email/SMS alerts from anywhere, you need an active COMET Cloud subscription: every sensor includes a 3-month free trial, then it renews at a low annual rate. If you'd rather not subscribe long-term, the sensor's JSON, XML, Modbus TCP and SNMP outputs let your own IT system log the data instead.
A WiFi sensor has no meaningful onboard storage of its own — it shows the current reading locally, and needs COMET Cloud (or your own server, via JSON/XML/Modbus TCP/SNMP) to keep a logged history, trend graphs or alerts. A data logger stores its full reading history on the device itself, with no subscription or ongoing connectivity required, and you download the data when needed — better suited to standalone or intermittent-connectivity sites. See our Wireless Data Loggers range for that use case.
The range covers temperature, relative humidity, CO2 and barometric pressure — individually or combined — as ambient units, remote-probe thermometers (single or 4-channel external Pt1000 probes) and combined T+RH+CO2+pressure models.
Yes — that's what they're built for. COMET WiFi sensors are used in warehouses, labs, server rooms, cold storage, schools and production facilities. They ship with a calibration certificate from the manufacturer, unlike consumer smart-home sensors.
Yes. COMET Cloud supports multiple sensors and sites on a single dashboard, with configurable email/SMS alarm thresholds per sensor — suited to businesses monitoring several rooms, sites or client locations.
The current reading is available locally over WiFi with no internet connection required — check it on the sensor's display, local web page or an app on the same network. Internet access (and an active COMET Cloud subscription) is only needed for logged history, trend graphs or alerts from outside the local network.
Yes. Pacific Sensor Technologies holds local stock, ships Australia-wide, and calibrates through our own NATA-accredited lab - so setup help, service and recalibration don't depend on overseas turnaround.
