Tekelek LoRaWAN Fill-Level Sensor

Tekelek‘s LoRaWAN Fill-Level Sensor offers a flexible battery-operated device; ideal for smart waste management or monitoring tank-levels of solid materials. Designed to help reduce the cost of waste collection, the Tekelek fill-level sensor enables greater operational efficiency.

For accurate, reliable fill-level monitoring, the IoT Fill-Level Sensor has the option to set low and high level alarms. This means that the device can alert you when a waste bin is full, or a feedstock tank is empty. It uses ultrasound to monitor the level of solid contents, but can be paired with a liquid-level sensor to monitor liquid feedstocks.

Utilising LoRaWAN® technology the TEK839 LoRaWAN Fill-Level Sensor has a battery life of up to 14 years and can transfer data up to 15km.
