Sensor for micro:bit (micro:bit sensor board)

Description:

The MonkMakes Sensor Board for micro:bit allows you to sense sound level, temperature and light level.

Features

  • 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.
  • LED ‘power on’ indicator
  • Reverse polarity protection
  • All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips.

Getting Started

Connecting to your micro:bit

You only have to wire up the sensors that you are actually using, but you could wire all the sensors up as shown below. The code examples below assume that pin 0 is used for sound, pin 1 for temperature and pin 2 for light. You can use any pin for any of the sensors, but remember to modify the code to match the pin you are using.

Sound

The Sensor for micro:bit uses a MEMs (microphone on a chip) and a pre-amplifier. The output of the sound sensor is connected to an analog input where it can be sampled. The sound signal varies about the 1.5V level. So, silence will produce an analog output of around 1.5V. When there is sound the analog readings will oscillate above and below the 1.5V level like this:

This is why 511 is subtracted from the readings in the code examples below.

Here is an example of using the Sensor Board to display a bargraph to indicate the sound level. Click on the image below to try it out. Making a noise into the microphone will make the LEDs dance.

MicroPython

from microbit import *

def bargraph(a):
display.clear()
for y in range(0, 5):
if a > y:
for x in range(0, 5):
display.set_pixel(x, 4-y, 9)

while True:
sound_level = (pin0.read_analog() - 511) / 100
bargraph(sound_level)

Temperature

The Sensor for micro:bit uses a thermistor to measure temperature. The temperature output from the board is a voltage that indicates the temperature. This is then measured using an analog input on the micro:bit.

The calculations for converting this voltage reading to an actual temperature are quite complicated and so the code examples here will only give a rough idea of temperature.

If you want your temperatures in Fahrenheit, then multiply the temperature in degrees C by 9, divide the result by 5 and then add 32.

JAVASCRIPT BLOCKS EDITOR

This is an example of using the Sensor Board to display the temperature, try putting your finger on the temperature sensor to warm it up. You can run the example below by clicking on it.

MicroPython

from microbit import *

while True:
reading = pin1.read_analog()
temp_c = int(reading / 13.33 - 14)
display.scroll(str(temp_c))
sleep(500)

Light

The light sensor uses a phototransistor to measure the light level and produces an output voltage that increases as the light level increases. Here is a guide to the kind of light level you might get from the sensor under different conditions (0 to 1023).

  • Dark 0 to 3
  • Dimly lit room 6 to 10
  • Indoors directly under a light 10 to 50
  • Outdoors (dull day) 100 to 200
  • Outdoors (sunny day) 800 to 900

Even though the maximum analog read value is 1023, the maximum reading from this sensor is around 900.

Here is an example of using the Sensor Board to display a bargraph to indicate the light level. Click on the image below to try it out. Put your finger over the light sensor to make it dark or shine a flash-light onto it to make more LEDs light up.

MicroPython

from microbit import *

def bargraph(a):
display.clear()
for y in range(0, 5):
if a > y:
for x in range(0, 5):
display.set_pixel(x, 4-y, 9)

while True:
light_level = pin2.read_analog() / 10
bargraph(light_level)

The BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass, LED display, and Bluetooth technology built in.

It measures 4cm by 5cm, is available in a range of colours, and designed to be fun and easy to use. It can be coded with something simple in seconds – like lighting up its LEDs or displaying a pattern – with no prior knowledge of computing.

It also connects to other devices, sensors, kits and objects, and is a companion to Arduino, Galileo, Kano, littleBits and Raspberry Pi, acting as a spring board to more complex learning.

Each element is completely programmable via easy-to-use software on a dedicated website that can be accessed from a PC, tablet or mobile.

  • Upgraded processor (nRF52833)
    • 64MHz Arm Cortex-M4 FPU (over 4 times faster!)
    • 512KB Flash storage on board
    • 128KB RAM
  • MEMS Microphone with LED indicator and on-board speaker
  • 5x5 LED matrix display
  • Touch sensitive logo "button"
  • Accelerometer/compass
  • Light and temperature sensors
  • Sleep/off mode for batteries powered projects (w/ LED indicator)
  • Up to 200mA of current for external accessories
  • Bluetooth 5.0 radio allowing micro:bits to talk to each other
  • Notched edge connector (easier to connect things like crocodile clips and conductive thread)
  • Dimensions: 52mm x 42mm x 11.7mm

It's the same shape and size so should be already familiar to countless teachers and learners, and also compatible with the vast majority of add-on boards and accessories.

How does the BBC micro:bit work?

It's programmed with beginner friendly, drag and drop interface MakeCode with the option to progress into MicroPython later on, opening up even more programming possibilities!

It's packed with inputs, outputs, sensors and radio communication features that can be combined into and endless variety of projects.

Inputs and outputs: An important part of any computer system. As a very small computer, the BBC micro:bit has plenty of inputs and outputs to learn about and use.

LEDs: An LED, or light-emitting diode is an output device that gives off light. Your BBC micro:bit has a display of 25 LEDs for you to program.

Buttons: A very common input device. Your micro:bit has two "clicky" buttons and a touch sensitive button you can program, and a reset button.

Radio: A way of sending and receiving messages and BBC micro:bits can use radio waves to communicate with each other.

Accelerometer: A motion sensor that measures movement. The accelerometer in your BBC micro:bit detects when you tilt it left to right, backwards and forwards and up and down.

Compass: An input sensor that detects magnetic fields. Your BBC micro:bit has an inbuilt compass that can detect the direction in which it is facing.

Light sensor: An input device that measures light levels. Your BBC micro:bit uses the LEDs to sense the levels of light and lets you program your micro:bit as a light sensor.

Temperature sensor: An input device that measures temperature. Your BBC micro:bit has a temperature sensor inside the processor which can give you an approximation of the air temperature.

Pins: On the bottom edge of your BBC micro:bit there are 25 gold strips, called pins. These pins allow you to really get creative. You can create circuits, connect external things like buzzers and motors and make your own fun projects.

Sound: Your BBC micro:bit can be programmed to make a wide variety of sounds - from single notes, tones and beats to your own musical compositions.

Requires:

  • microB USB Cable for programming
  • Computer/laptop with Internet access
