Here's everything we used:
- 1x NodeMCU board (Price: $8)
- 1x Relay (Price: $6)
- 1x TMP36 Temperature sensor (Price: $ 2)
- 1x HC-SR501 PIR Sensor (Price: $2)
- 9-12V 1.0A DC Adapter (Price: $6)
- 3.3V/5V power supply module (Price: $6)
- 1x Breadboard (Price: $5)
- Jumper/electric wires (Price: $1)
- Bidirectional logic-level shifter (Price: $1)
- 1x bulb/appliance that you want to control (Price: $2)
We also did one with Raspberry Pi and Alexa which is really fun.
