Pretrace’s S20 is a wireless photoelectric smoke sensor with communication capability over Cat M, NB IoT, LoRaWAN, and Sigfox networks. It is designed to provide comprehensive environmental monitoring and security. Alarms will be triggered when it detects smoke or when the environmental temperature exceeds the threshold. A sound alarm of up to 83dB will be activated on-site, and the alert will be reported to a remote server application.

To accommodate a wider range of applications, the S20 offers the option to include a CO2 sensor, human detection, and a camera with night vision.
