Editor: arduino IDE
Motherboard: arduino uno
Sensor:
0.96-inch OLED screen (four legs)
sound module
Soil temperature and humidity module
DS18B20 temperature module (waterproof is used here)
Photoresistor module (the one bought with three pins can only display high and low, it can be replaced with four pins to display numbers)
arduino expansion board (depending on personal needs)
Dupont line (female to female, male to female)
Function: It can display the sensor data on the OLED screen and simulate the pattern corresponding to the state of the plant.
You can set the zero point by yourself
(If you buy a small amount, you can just buy a pdd, which is easily within 100 yuan. You can also buy a wifi module and make it an app host)
