Wireless barometer & temperature sensor

The CMA Science wireless barometer & temperature sensor simultaneously measures absolute atmospheric pressure and temperature, with ranges of -30 to 110 kPa and -40 to 125°C.
The sensor is equipped with an OLED color display that shows sensor information and measured values. This makes the sensor suitable for use as a standalone measuring instrument.

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.

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.

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
