Wireless temperature, humidity and atmospheric pressure loggers are used for indoor measurements, among others in warehouses, hospitals, museums or airports.
You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system.
- Temperature: -35 to +70°C, accuracy: up to 0.4°C in the -20°C to +70°C range and 0.5°C in the -35°C to -20°C range
- Humidity: 0 to 99% RH, accuracy up to 4% in the range of 0 to 80%
- Pressure: 300 to 1100 hPa, absolute accuracy +/- 3 hPa at 0 to + 65°C, relative +/- 0.12 hPa at 0 to + 65°C, p = 800 - 900 hPa
- Measurement period: 1 minute – 10 days (configurable by the user)
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Battery ensures up to 5 years of maintenance-free operation
- Add Efento Gateway and Efento Cloud to build a real time monitoring system. The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
