Wireless temperature and humidity sensors

Measure and monitor the ambient thermal conditions in each room or zone

Our wireless multi-sensors measure the ambient temperature and relative humidity in each room, cabinet or zone. The small, solar-powered sensors use ultra-low-power wireless technology, making them easy to install and very low maintenance. Now with battery back-up for low-light environments.


Get accurate, reliable climate updates

The sensor sends instant updates if the temperature changes by more than 0.5°C or humidity changes by more than 2%


Solar-powered with battery back-up for easy install

The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.


Access near real-time data locally or in the cloud

Temperature and humidity data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.

If you’re looking to order sensors for a trial, project or have regular requirements, please contact our friendly team to discuss pricing options.


  • Small, discreet sensors simply stick to the wall or cabinet
  • Measures temperature and relative humidity:
    • Temperature 0-40ºC (+/- 0.5ºC between 17-27°C otherwise +/- 1°C)
    • Humidity 0-100% RH (+/- 5% between 30-70%)
  • Reports if the temperature changes by more than 0.5°C or humidity changes by more than 2%, otherwise updates every 15 minutes
  • Solar-powered using ambient room light – optimally angled to absorb light – with a battery back-up for periodic low-light conditions. Batteries typically last up to 10 years
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
    • 868 MHz for Europe (RED)
    • 902 MHz for North America (FCC) and Canada (IC)
    • 928 MHz for Japan (ARIB specification)
  • EnOcean Equipment Profile (EEP): A5-04-01
  • No recurring fees. Access the data through your chosen platform, without any additional costs from Pressac
  • Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures
  • Dimensions: 76.5 x 28 x 17.5 mm (approx)
