The Monnit Wi-Fi voltage meter meassures voltage up to 1.2 volts DC by
connecting the leads on the 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, 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 meter is really
just a “voltage observer”. Cannot be used for AC voltage
This version of the Wi-Fi sensor uses a detachable high gain antenna
to provide a 20-30% increase in range over the standard Wi-Fi
sensor.Email / SMS messages can be configured by the
system to alert the user immediately when a parameter has
WARNING: Use caution when interfacing to the Monnit Wireless Voltage
Meter. Negative voltages, any kind of AC Voltages, or DC Voltage
exceeding 3.6V WILL DAMAGE the electronics of the Monnit Wireless
Sensor. Monnit is not responsible for troubleshooting, replacing or
reimbursing damages incurred by disregarding this warning.
- 802.11 b/g (2.412 - 2.484 GHz)
- Up to 250 ft. (Typical to standard Wi-Fi devices)
- Open, WEP, WPA, WPA2 Security Standards
- High gain, RPSMA antenna provides 20-30% increase in range.
- Interfaces with other devices up to 1.2 VDC
* Actual range may vary depending on environment.
** Battery life is affected by reporting frequency (heartbeat), sensor type, Wi-Fi security type, distance from
Wi-Fi router and other variables.
In order to program the sensor to connect to your wif-fi network,
you will need a Wi-Fi programming cable and the free MoWi setup
utility. The MoWi setup utility is currently available for Windows. Mac and Linux are not currently supported!
