The intermittent controller introduced in this example can automatically control the electric power devices such as electric heaters, humidifiers, and single-phase AC motors to make them work intermittently. Circuit working principle The in....
The connection of the thermostat is nothing more than the connection of the two main leads of input and output. As long as the power supply is normal, it can work. High-end, complex thermostats have more functions, mainly to give signals to....
The temperature controller circuit uses LED light-emitting diodes to display the temperature in sections. When the temperature reaches the highest temperature displayed, the heating device automatically stops working. The temperature contro....
The thermostat controller consists of the thermistor Rt1, Rt2, NE555 time base circuit, temperature range adjustment resistors RP1, RP2 and the control actuator. The circuit is shown in Figure 1 (click here to download the schematic). Rt1 a....
