The Itokii Wireless Resistance Sensor outputs the resistance across a load. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the load resistor, wait for it to stabilize, and convert the analog data, mathematically compute the resistance and transmit the data to the gateway, where it is then logged into a cloud service. The user can configure defined thresholds and have the system alert on threshold breaches. Data is recorded in Ohms.
- Measures up to 145 KOhms.
- Accurate to ± 1.5% (FS) with user calibration.
- Interfaces with any variable resistance device.
