AHOY SYSTEMS is a manufacturer for LoRa/LoRaWAN based Passive Infrared(PIR) sensors. These are motion sensors that can pick up activity in an area and send an uplink to a LoRaWAN or LoRa network.
LoRa-PIR(Passive InfraRed) sensor is a low-cost human motion detection sensor which can be used to report presence/absence of human movement open/close state of a building pir, cabinet pir or drawer.
The pir sensor is a versatile device with 2-way LoRa/LoRaWAN communication. This device can be configured remotely over-the-air to work as per requirements for instance it can be configured to report opening/closing instances during specific time of the day or day of the week and also detect and report duration of a particular state.
Variants of the pir sensor also come with short-range 433Mhz radio that can trigger events in other devices as soon as activity is detected in the primary sensor.top
