Compact, accurate and up to 10 years maintenance-free.
The SenseAnywhere AiroSensor is a very compact, accurate and robust wireless data logger that continuously monitors temperature, relative humidity and motion. The sensor communicates automatically with the cloud, where all data is safely stored — without you having to read out or transfer anything yourself. Thanks to its ultra-low-power design, the AiroSensor operates maintenance-free for up to 10 years, without a battery change. This version is particularly well suited for accurately tracking relative humidity in storage spaces.
Two models, one reliable solution
- AiroSensor 20-20-24 — compact model, range up to 100 meters (line-of-sight) to an Access Point.
- AiroSensor 20-20-25 — equipped with antenna, range up to 600 meters (line-of-sight) to an Access Point. Ideal for larger spaces or locations where the distance to the Access Point is greater.
What is the AiroSensor T/RH suitable for?
Thanks to the combination of accurate temperature and humidity measurement, together with motion detection, the AiroSensor is suitable for a wide range of applications:
- Pharmaceutical storage (Pharma)
- Mapping of storage spaces and warehouses
- Laboratories
- Food industry
Key features
Real-time monitoring with instant alerting As soon as a measured value falls outside the set limits, you immediately receive an alert. This allows you to act quickly before damage occurs to moisture-sensitive or temperature-sensitive products.
Accurate humidity measurement Measuring range of 0 to 100% RH (non-condensing), with a typical accuracy of ±2% RH (max. ±3% RH between 0-80% RH, max. ±4.5% RH between 80-100% RH) and a resolution of 0.1%.
Motion detection The built-in 3-axis accelerometer (sensitivity programmable from 0g to 16g) records movements of the sensor, providing extra insight during transport or unwanted displacement.
Magnetic contact and SwitchHolder The accompanying holder (SwitchHolder) detects when the sensor is placed or removed, and lets you use a slide switch to turn the alarm on/off or activate a start/stop trip report.
Very long battery life Up to 10 years of maintenance-free operation, or up to 1 million readings, thanks to the ultra-low-power design.
Robust and compact housing The PC-ABS housing is easy to clean and has protection rating IP62.
Easy mounting The holder is standard equipped with strong double-sided adhesive tape. For mounting in harsh conditions or on rough surfaces, two stainless steel screws are also included. Mounting on metal surfaces, reinforced concrete or in metal racks/cabinets is not recommended, as this can affect the wireless signal quality.
Meets international standards Certified to EN12830:2018 class 0.5 (storage & transport, Climatic environment type D), CE, EN300328 and EN55022.
2-year warranty All AiroSensor T/RH models carry a warranty period of 24 months.
