Wireless temperature sensors
Measure and monitor ongoing changes in ambient temperature in each room, cabinet or zone
Accurate & reliable temperature data
Our wireless temperature sensors measure the ambient temperature 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. Optional battery back-up available for low-light environments.

Temperature Sensor FAQs
What type of temperature sensors do you offer?
At Pressac we provide multiple temperature sensing solutions:
- Standard wireless temperature sensors for ambient monitoring.
- Wireless temperature & humidity sensors for combined environmental sensing.
- CO2, Temperature, and Humidity sensors for a full view of IAQ conditions.
- Industrial three-channel temperature sensors for surface, liquid or ambient readings across three locations.
How do your wireless temperature sensors work?
Pressac wireless temperature sensors measure ambient temperature using ultra-low-power wireless technology and transmit readings via the EnOcean protocol. Our temperature sensors are solar-powered with optional battery back-up for low-light conditions, requiring no wiring and minimal ongoing maintenance.
What communication protocols are supported by Pressac temperature sensors?
Pressac temperature sensors use the EnOcean wireless protocol, transmitting securely using AES-128 encryption across licence-free ISM bands (for example 868 MHz in Europe). Data can be collected locally or integrated into cloud platforms via gateways supporting MQTT, AWS IoT Core, or Azure IoT Hub.
What temperature range and accuracy can I expect from the standard wireless temperature sensor?
Standard wireless temperature sensors typically measure from 0°C to 40°C with an accuracy of approximately ±0.5°C in normal room conditions (17–27°C) and up to ±1°C outside that range.
What are the environmental and installation requirements for these sensors?
For optimal readings, the sensor should be placed away from direct heat sources (radiators, vents) and strong air movement. Solar-only versions require exposure to ambient light for energy harvesting; variants with battery back-up are recommended for low-light interiors.
Can Pressac temperature sensors be integrated into my building management system?
Yes. Sensor data can be accessed in a variety of ways including direct cloud integration (via MQTT to Azure, AWS etc.), local networks, or through custom software platforms. The solution is system-agnostic, supporting flexible integration into existing BMS or analytics platforms.
Do I need recurring subscriptions or fees to access temperature data?
No. Pressac does not charge recurring subscription fees for sensor data access. You can pull data directly via your chosen platform, gateway or cloud integration without ongoing costs from Pressac.
How often do sensors update temperature data?
Standard sensors transmit readings dynamically:
- If temperature changes by more than 0.5°C, they send an immediate update.
- Otherwise, they transmit at regular intervals (commonly every 15 minutes).
Are your temperature sensors secure?
Yes. The wireless protocol supports AES-128 encryption, and secure communication modes can be configured where supported by receiving devices.
Do your sensors require maintenance?
Maintenance for our temperature sensors is minimal. Battery-backup versions may need replacement after several years, but our sensors are factory-calibrated and do not require routine recalibration.
How do our temperature sensors work?
Our technology is system agnostic, the data from our sensors can be used in any way you need. There are different options to choose from, making it easy to get your data in the way that’s right for you.

Why Choose Pressac Temperature Sensors?
Our IoT temperature sensors provide accurate, real-time insights into ambient temperature within a room or zone. Trusted by businesses, schools, and commercial organisations, they make it simple to monitor environments, improve comfort, and optimise building performance.
Accurate Temperature Monitoring
Our wireless temperature sensors provide continuous, reliable measurement of indoor conditions. They deliver real-time temperature data to help maintain occupant comfort, optimise energy use and support compliance with building performance standards. With consistent, high-accuracy readings, you gain a clear and dependable view of your internal environment.
Quick and Wireless Installation
Compact and unobtrusive, the sensors can be easily wall-mounted using the supplied backplate. They transmit temperature data wirelessly using the EnOcean protocol, enabling rapid, cable-free installation. This makes it simple to deploy sensors at scale across new or existing buildings without disruption.
Low-Energy, Low-Maintenance Operation
Designed for ultra-low-power performance, the sensors offer long operational life with minimal maintenance. Solar-powered models harvest energy from ambient light, with a battery back-up option available for lower-light environments. This reduces the need for routine servicing, helping to lower running costs and avoid unnecessary downtime.
