Wireless temperature sensors

Wireless temperature sensors are used to monitor the temperature in buildings, refrigerators, laboratories, hospitals and clinics. Our portfolio of wireless temperature sensors include devices with internal sensors and external probes for very low and very high temperatures, wireless temperature sensors with Pt1000 probes and loggers which measure temperature and other physical values (e.g. humidity, air pressure, VOC). We can customise the type and length of external temperature probes to your needs. Efento’s wireless temperature loggers are based on Bluetooth Low Energy, NB-IoT and LTE-M technologies. Sensors can be used with Efento Cloud or any other IoT platform.
