Micro:bit and LM75 temperature sensor example

The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector. The host can query the LM75 through its I²C interface to read temperature at any time. The open-drain overtemperature output (OS) sinks current when the programmable temperature limit is exceeded. The...

Micro:bit and GY-21P module example

The GY-21P is an interesting module in that it combines a BMP280 sensor and an SI7021 sensor. The on-board BMP280+SI7021 sensor measures atmospheric pressure from 30kPa to 110kPa as well.

Micro:bit and BMP280 barometric pressure sensor example

BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption.

The MCP3421 A/D converter and the Micro:bit

The MCP3421 ADC can be used for various high accuracy analog-to-digital data conversion applications where ease of use, low power consumption and small footprint are major considerations.The MCP3421 is a single channel low-noise, high accuracy delta-sigma A/D converter with differential inputs and up to 18...

Micro:bit and L9110 fan module example

In this example we connect a Micro:bit to a L9110 fan module. This is a commonly found, basic low cost module which consists of an L9110 chip and a small.

LIS2DH12 linear accelerometer Micro:bit example

In this article we connect a LIS2DH12 to a Micro:bit The LIS2DH12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I2C/SPI serial interface standard output..
