Design with Thermostat KSD301 145C in Cirkit DesignerThe Thermostat KSD301 145C is a temperature-sensitive thermal switch manufactured by KSD301. It is designed to open or close an electrical circuit when the ambient temperature reaches a preset threshold of 145°C. This component is widely used in temperature control systems for appliances such as electric kettles, heaters, ovens, and other electronic devices requiring thermal regulation.
This circuit is a temperature control system that uses a thermocouple to measure temperature and a PID controller to regulate it. The PID controller drives a solid-state relay (SSR) to control an external load, with power supplied through an AC inlet socket.

This circuit is a temperature control system that uses a temperature controller to regulate a heating titanium resistor via a solid-state relay (SSR). The power transformer supplies the necessary voltage to the temperature controller, which in turn controls the SSR to manage the heating element.

This circuit utilizes an ESP32 microcontroller to monitor temperature via an LM35 sensor and control a fan based on the temperature readings. The data is displayed on a 0.96" OLED screen, while a MOC3041 optoisolator and a BT139 TRIAC manage the fan's operation, allowing for phase control based on the detected temperature. The circuit is designed for efficient temperature regulation in a 220V AC environment.

This circuit is a smart environmental control system using an Arduino UNO. It monitors temperature and humidity with a DHT11 sensor, displays data on an OLED screen, and controls an exhaust fan and air heater via a relay module based on sensor readings. The system also includes a real-time clock for time-based operations.

The KSD301 thermostat has two terminals for electrical connections. The configuration depends on the contact type (NC or NO):
| Pin | Description |
|---|---|
| Pin 1 | Input terminal for the electrical circuit |
| Pin 2 | Output terminal for the electrical circuit |
The KSD301 can be used with an Arduino UNO to monitor its switching state. Below is an example circuit and code:
// Thermostat KSD301 Monitoring with Arduino UNO
// Pin Definitions
const int thermostatPin = 2; // Digital pin connected to KSD301
void setup() {
pinMode(thermostatPin, INPUT); // Set thermostat pin as input
Serial.begin(9600); // Initialize serial communication
}
void loop() {
int state = digitalRead(thermostatPin); // Read the thermostat state
if (state == HIGH) {
// Thermostat is open (temperature above 145°C for NC type)
Serial.println("Thermostat is OPEN: Temperature above 145°C");
} else {
// Thermostat is closed (temperature below 145°C for NC type)
Serial.println("Thermostat is CLOSED: Temperature below 145°C");
}
delay(1000); // Wait 1 second before reading again
}
Thermostat Does Not Switch at 145°C:
Circuit Does Not Reset Automatically:
Overheating or Circuit Damage:
Q1: Can the KSD301 be used for DC circuits?
A1: While the KSD301 is rated for AC circuits, it can be used in low-voltage DC circuits. Ensure the current does not exceed 10A.
Q2: How do I identify NC or NO types?
A2: Use a multimeter to check continuity at room temperature. NC types will show continuity, while NO types will not.
Q3: Can the thermostat be adjusted to a different temperature?
A3: No, the KSD301 is factory-set to 145°C and cannot be adjusted.
Q4: Is the KSD301 waterproof?
A4: No, the KSD301 is not waterproof. Avoid exposing it to moisture or liquids.
