Four common temperature sensors: thermocouple (–184ºC to +2300ºC, widest range), RTD (–200ºC to +850ºC, linear/accurate), thermistor, and semiconductor (high accuracy, both <200℃). Temperature sensing is vital for petrochemical, automotive, aerospace, defense, and consumer electronics industries.
1. Example Code for micro:bit-Air Temperature Detector
Put two pots of plants with same growth under different temperature conditions. Record their growth situations.
2. Example Code for micro:bit-High Temperature Alarm
When the temperature is detected to be over 35℃, the fan starts to work and the buzzer buzzes to alarm people.
3. Example Code for micro:bit-Temperature Indicator
When the temperature is detected to be below 25℃，the green LED turns on. If the temperature is within 25℃to 35℃, the blue LED turns on, if temperature over 35℃, the red LED turns on.
