This module includes the component BME280 that is translated into a digital signal.
The equipment uses the two I2C and SPI interfaces. The BME280 does not allow the module to be used as an altimeter as opposed to its successor BMP280.
Its 5-pin straight connector allows easy connection to other electronic boards. BME280 Digital Temperature Humidity Barometric Pressure Module features:
- Interfaces:
- I2C (up to 3.4 MHz)
- SPI (up to 10 MHz)
- Supply voltage: 1.8-5VDC
- Module operating range:
- Temperature: -40ºC to + 85ºC
- Humidity: 0-100%
- Pressure: 300-1100 hPa
- Resolution of the measures:
- Temperature: 0.01ºC
- Humidity: 0.008%
- Pressure: 0. 18Pa
- Accuracy of the measures:
- Temperature: +/>

This Reed switch module uses a small device called a reed switch.
When the device is exposed to a magnetic field, the two ferrous materials inside the switch come together and the switch closes. When the magnetic field is removed the switch opens. The operating mode: - When exposed to a magnetic field the DO output is high
- Power supply: 3.3-5V
- Contact type: SPST-NO (normally open)
- Use temperature: -20ºC to + 80ºC
- Type Output: Digital (1 - 0)
- PCB dimensions: 32 x 14 mm
