Monnit WIT™ Wireless Analog Voltage Sensor   Buy Wireless Analog Voltage Sensors!

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. **
     
  • Interfaces with other devices up to 1.25 DCV.
  • Operating temperature: -20° to 60°C (-4° to 140°F)
  • Small size is ideal for embedded applications.

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting
    frequency and other variables.

WARNING: Use caution when interfacing to the Monnit WIT Analog Voltage sensor. Negative voltages, any kind of AC Voltages, or DC Voltage exceeding 3.6V WILL DAMAGE the electronics of the Monnit WIT. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.

Need Longer Battery Life?
Monnit WIT2 Sensors provide the same features and benefits of our standard sensors but with the added value of AA batteries. The AA battery option is more robust at a wider temperature range and provides extremely long life for quicker heartbeats.
  • 2 replaceable AA 1.5V batteries.
  • At 1 hour heartbeat setting, included AA batteries will last more than 4 Years. **
  • Robust sensor housing.
