The Wireless Resistance Sensor reports the resistance across a load. It can be connected to any kind of passive (no voltage) resistance load. • Measures up to 250k Ohms. • Accurate to ± 2% (FS) with user calibration. • Interfaces with any purely resistive and passive load. The Wireless Resistance Sensor reads the resistance across any resistive load and reports back the measured resistance. The resistance sensor leads are meant to connect to passive devices only, connecting the sensor leads to any voltage or power source may damage the sensor. It is programmed to sleep for a user-given time interval (heartbeat) and then wake up, convert the analog data, mathematically compute the resistance, and transmit the data to the gateway, where it is then logged into the cloud service. The user can con igure de ined thresholds and have the system alert on threshold breaches.
