### 1. W1209 Digital Thermostat Temperature Controller
The W1209 digital thermostat temperature controller is a microprocessor-based device that measures temperature and controls the relay output accordingly.
The device features a 3-digit, 7-segment LED display that shows the current temperature reading.
It has a built-in temperature sensor (NTC thermistor) that measures temperatures ranging from -50C to 110C (-58F to 230F) with an accuracy of 1C.
heating and cooling. The relay output can be used to control devices such as fans, heating elements, or alarms.
The device allows for hysteresis setting, which enables the user to set a temperature difference between the on and off points of the relay output.
The W1209 also features a calibration function to ensure accurate temperature readings.
### 2. 12V 2A Power Adapter
The 12V 2A power adapter is a switching power supply that provides a stable output voltage of 12V DC with a maximum current rating of 2A.
The adapter is designed to power the W1209 digital thermostat temperature controller and other devices in the kit.
It features a compact design and is energy-efficient, making it suitable for IoT and automation applications.
### 3. 12V DC 0.15A Fan
The 12V DC fan is a compact, low-power cooling fan designed to provide airflow for temperature control applications.
The fan has a maximum power rating of 0.15A and operates at 12V DC.
It is suitable for use with the W1209 digital thermostat temperature controller to provide cooling or ventilation in applications such as temperature control systems, incubators, or CNC machines.
### 4. DC Female Jack/Splitter
The DC female jack/splitter is a connectivity component that allows multiple devices to share the same power source.
It features a single female DC jack input and multiple female DC jack outputs, making it suitable for distributing power to multiple devices.
### 5. Alligator Clips
The alligator clips are a pair of flexible, insulated clips with metal tips that can be used to connect devices to the power source or other components.
They are suitable for use with the DC female jack/splitter to provide a convenient and temporary connection method.

#define FAN_PIN 3 // Pin connected to the fan's control pinvoid setup() {
pinMode(THERMOSTAT_PIN, INPUT);
pinMode(FAN_PIN, OUTPUT);
}void loop() {
int temperature = getTemperature();
if (temperature > 25) { // Set desired temperature threshold
digitalWrite(FAN_PIN, HIGH); // Turn on the fan
} else {
digitalWrite(FAN_PIN, LOW); // Turn off the fan
}
delay(1000); // Wait 1 second before taking the next reading
}int getTemperature() {
// Read the temperature value from the thermostat's signal pin
int temperature = analogRead(THERMOSTAT_PIN);
return temperature;

GPIO.setup(FAN_PIN, GPIO.OUT)while True:
# Read the temperature value from the thermostat's signal pin
temperature = read_temperature()if temperature > 25: # Set desired temperature threshold
GPIO.output(FAN_PIN, GPIO.HIGH) # Turn on the fan
else:
GPIO.output(FAN_PIN, GPIO.LOW) # Turn off the fantime.sleep(1) # Wait 1 second before taking the next readingdef read_temperature():
