Description
This wireless barometer & temperature sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks, and mobile devices (Android and iOS).
The sensor converts measured pressure and temperature values into digital values. The sensor comes factory-calibrated in kPa and °C.
When using the Coach program, the predefined calibration can be shifted using the “Set Value” option.
Technical specifications:
- Measuring ranges: -30 to 110 kPa / -40 to 125 °C
- Accuracy: 0.4 kPa / 0.2 °C
- Warrantee: 36 months
- OLED display: 0.96” 128 x 64px
- Maximal sampling rate: 10 Hz
- Battery life: 13h when full (rechargeable)
- Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0
All specifications of the sensor are described it its Product manual, see downloads.
Suggested experiments:
- Measure air pressure over time to observe daily fluctuations
- Calculate altitude changes by moving the sensor to different floors or heights
- Measure pressure changes in a closed space, e.g. (bell jar) when air is added or removed
- Attach the sensor to a small balloon or drone to study atmospheric pressure at different altitudes
- Map the elevation profile of a hiking trail using atmospheric pressure measurements
