  • Sensor can “transmit now” using power switch.
  • Metal Enclosure with plastic end caps.*
  • Battery Life:  Appropriately 2 to 4 years when transmitting once per hour.*
  • See industrial sensor version for 10 year battery life.
  • Voltage Sensing Range: 0 – 1.20 VDC.  Note:  most industrial analog sensor outputs are from 0 – 1.25 volts.  This sensor’s upper range is 1.20 volts, not the standard 1.25 volts.
  • Electronics Operating Temperature:  -40° to 85°C (-40° to 185°F)
  • Radio range:  Up to 300 feet in open air.  Repeaters are available to extend range.
  • FCC, IC certified.
  • 915 MHz radio (North America).  Will not interfere with 2.4 GHz WiFi networks.  Contact us if outside North America.
  • Battery:  Standard Tadiran TL-5276/W battery.
  • Sensor Size (in inches):  1.76 wide x 2.1 high x 1.0 deep.  Wire antenna: 3.6 inches long.
  • Optional mounting tabs extend another 0.5 inches from both the top and bottom of the sensor.
  • Sensor is not sealed.  See industrial version for an IP65- water and dust protected enclosure.

Standard version of web-based SensorManager.com software supports fast and easy configuration of:

  • Transmission intervals from 10 minutes to days.
  • Text and email alerts.
  • Custom sensor names.
  • Data graphing with user select-able time frames.  Graphs highlight data points outside alert limits.  Zoom-in function.
  • Download data to spreadsheets.
  • Special “Aware State” function sends sensor readings at a faster rate in critical (user defined) ranges.
  • Give it a test drive on our live demonstration Wireless Sensor Network (WSN)… go to www.SensorManager.com     User Name:  demo1234    Password:  demo1234

*See industrial version for sealed enclosure and battery life of up to 10 years.  Battery life is reduced at temperatures outside the range of +10°C to +50°C (+50°F to +122°F).

This wireless sensor is ideal for monitoring:

  • Voltage monitoring.
  • Failure notification.
  • Over or under voltage sensing.
