Manhole cover position sensor (inclinometer)

  • The antenna is specially designed to work from under the hatch cover. Works even from a completely metal environment - on hatches with installed pods
  • Designed to detect the fact of a shift or opening of the hatch cover
  • Demanded to control the opening of hatches for cable, waste and storm sewers
  • For control, a specially tuned accelerometer is used, which does not respond to vibration from passing cars
  • There are several versions of the sensor housing (selected individually for the task)
  • Sensors can work in LPWAN, as well as in a two-layer system, where sensors use the BLE protocol to communicate with a repeater, which in turn transmits a signal to LPWAN
  • Powered by an ER14505 battery (included) rated for 50,000 messages, guaranteeing a minimum of 5 years of operation (one message per hour)
