The LoRa PIR sensor based on passive infrared technology to detect a motion or occupancy. It can detect whether there is movement within the range of 6-8m and send the changes via LoRaWAN* network.

Up to 5Km communication range in an open environment; LCD Screen indicates reading, power percentage, allowance, valve, and signal status. Long-lasting battery life of up to 3 years; Capable of saving over 10,000+ historical operation records locally; Compatible with standard LoRaWAN® gateways and third-party network server platforms; Fast connection with HKT LoRaWAN® gateway and cloud platform without additional configuration.


This rumen bolus sensor, based on LoRaWAN, is designed to collect cows’ activity, rumen temperature, and movement. The bolus material is environmentally friendly and harmless to the animal.
After insertion, the rumen bolus will automatically transmit data to LoRa base stations and cloud-based platforms, allowing users to access this information at any time, from anywhere.
