Sensor board for Micro:bit

Micro:bit sensing the world with sensor board

The MonkMakes Sensor Board can be used to detect sound levels, light levels and temperature. It features ring connector pads so it can be wired with alligator clip. It is so easy to wire it on a the Micro:bit.

All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips

The board can be used to detect

Sound Level: It senses sounds with a MEMs based sensor. It is a microphone chip that also features a pre-amplifier circuit. You can then use the plot bar graph block in the Microsoft MakeCode editor to display the result on the microbits LED matrix.

Light Level: The light sensor is a photo-transistor that measure the light level and let the current flow into it depending of the quantity of light. This results into an output voltage that increases as the light level increases.

Temperature Level: The temperature output from the board also produce an voltage varying with the temperature. The voltage is measured with an analog input pin on the Micro:bit.

It has 3V and GND connectors on both sides of the board which make it possible to power another board, such as the Relay Board or Powered Speaker Board.

Feature

• LED power on indicator.
• Reverse polarity protection.
• Detects sound level with a MEMs (microphone on a chip) and a pre-amplifier.
• Temperature measured with thermistor.
• Light level detection with a photo-transistor (0 to 1023).
• Length: 63.2mm
• Width: 55.7mm.
• Thickness: 1.6mm.

All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips.

3V and GND connections can be made from either side and allow you to power a second board such as the MonkMakes Relay Board or MonkMakes Speaker.
