Description
The humidity 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.
The 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).
Technical specifications:
- Measuring ranges: humidity 0 .. 100% RH / temperature – 40 .. 125 °C
- Accuracy : ± 2% RH (@0 ~ 80%RH) / ± 0.25 °C (@-40 ~ 60°C)
- Warrantee: 36 months
- OLED display: 0.96” 128 x 64px
- Response time: 15 s at 25 °C in slowly flowing air
- Max. sample frequency: 60 Hz
- Battery life: 12h when fully charged (rechargeable)
- Connectivity: Bluetooth 5, Low Energy (Mac, Android, iOS), Bluetooth 2.1, Classic (Windows), or USB-C 2.0
Full sensor specifications can be found in the Product Manual, see Downloads.
Suggestions for science experiments:
- Measure indoor humidity and temperature over a day to observe daily fluctuations
- Compare humidity levels in different rooms of a school to see microclimate differences
- Track outdoor humidity and temperature changes and correlate with local weather reports
- Measure how quickly a sealed container reaches equilibrium humidity after adding water
- Study the effect of a fan or ventilation on humidity and temperature in a closed space
- Observe dew formation by cooling a surface and measuring the dew point
- Compare humidity readings in warm vs. cold environments to see how temperature affects relative humidity
- Monitor humidity and temperature in a greenhouse or terrarium over time
- Test how well an air humidifier works in different rooms
