Analog Voltage Sensor

The Monnit wireless analog voltage sensor interface is capable of measuring the voltage off another device, battery, or sensor, up to 1.25 DCV by connecting the leads on the Monnit WIT Analog Voltage sensor to the positive and ground terminals of the device being measured. Examples of interfacing devices include, but are not limited to: Strain Gauge, Pressure Transducer, RTD, Thermistor, or Thermocouple, Piezo Electric sensors, Photoresistor, Industrial Accelerometer, any kind of variable resistor, any kind of sensor that outputs a voltage, etc. If the device being measured is passive, the user must supply their own excitation voltage, as the Monnit WIT Analog Voltage sensor is really just a “voltage observer”. Cannot be used for AC voltage measurement.

Monnit WIT Wireless Sensor Specifications

900, 868 and 433MHz operating frequencies
250 - 300 ft. non-line-of-sight device range*
Replaceable 3.0V battery
At 1 hour heartbeat setting, coin
cell battery will last ~ 1-2 Years. **
