Description
The Manhole cover position sensor is an IoT device that detects the position of manhole covers and other metallic objects in real-time. The sensor provides accurate and timely information on whether the manhole cover is open or closed, which is essential for urban safety and maintenance purposes.
The sensor is designed to work in various conditions and environments, making it suitable for use in both urban and rural areas. Its compact and robust design allows it to withstand harsh weather conditions and heavy usage, making it ideal for monitoring manhole covers in high-traffic areas.
- 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)
