HD248-W Wireless Temperature Transmitter – Battery Powered for Remote IoT Monitoring
The HD248-W wireless temperature transmitter adopts micro-machined silicon sensor technology and ultra-low power design. It transmits temperature signals wirelessly to a control room via Zigbee or LoRa. With internal battery power and no external wiring required, it is ideal for remote monitoring applications where power supply is unavailable.
