Description: This topic is ensuring the safety of the solitary elderly. We want to use the water-proof temperature sensor to detect the temperature of drinking water to prevent the elderly from drinking too hot water. The suitable temperature of drinking water is 35-40 °C. Therefore, we set the Micro:bit code that Micro:bit produces a sound and the LED light on when the temperature sensor detects over 40°C of water. School: Laichikok Catholic Primary School (P.4)
