COMET W0932 – LoRaWAN temperature sensor with internal sensor + 2 external Pt1000 probes, -200 to +260 °C

COMET W0932 – battery-powered LoRaWAN temperature sensor with internal sensor + 2 external Pt1000 probes, –200 to +260 °C, IP65 

The COMET W0932 is a versatile, battery-powered 3-channel LoRaWAN temperature sensor – the ideal IoT solution for wireless, energy-efficient multi-point temperature monitoring in warehouses, cold chains, server rooms, technical centers, greenhouses, production halls, or distributed systems. With one internal sensor and two external Pt1000 probes (available separately or included in the package), it can simultaneously monitor different measurement points – e.g. room temperature + pipeline + outdoor temperature – all with one device, no wiring or power connection required.

The internal sensor measures from –30 to +60 °C (±0.4 °C), and the two external Pt1000 probes measure from –200 to +260 °C (±0.2 °C from –200 to +100 °C; ±0.2% of the reading above). All three values are transmitted wirelessly via LoRaWAN (Europe 863–870 MHz) at adjustable intervals (5 min to 24 h) to the COMET Cloud – where charts, data export, alarms, and remote configuration via app or browser are available. Two configurable alarm limits per channel with push notifications protect against critical temperatures. The internal antenna ensures reliable transmission – up to 15 km in open areas and 2 km in buildings.

The IP65 enclosure protects against dust and water jets – ideal for indoor and outdoor use. The integrated (replaceable) battery lasts from 3 to 10 years depending on the transmission interval. No wiring required – easy installation and startup. The COMET Cloud service is included free for 1 year (then 1 credit/year) with data storage and alarm features. An optional preconfigured LoRaWAN gateway is available – ready for immediate cloud connection.
