Digital temperature controller circuit and working Fig. 2 shows circuit diagram of the digital temperature controller. The circuit is built around microcontroller PIC16F877A (IC1), precision ...

The 555 timer IC remains iconic and widely used. Let's explore its enduring appeal through simple, fully tested 555 projects.

Figure 2 shows the system block diagram of the solution. The difference amplifier uses MCP6V01 auto-zeroed op amp to amplify the thermocouple’s EMF voltage. The CV REF is an internal comparator ...

Water Temperature Controller – Block Diagram The block diagram of this simple project is shown in Fig. 1 and its circuit diagram is in Fig. 2. The project is built around water temperature sensor ...

There is a push-button above the PI gains box allowing the operator to switch between manual and automatic control. The slider allows one to manually control the fan speed. When the "Save” button is ...

With the help of this model, we intend to publish a series of technical notes about the LTSpice modelling of several old-school temperature control analog circuits. Now this might not seem that ...

Over-temperature Warning: Yes (Flashing LED and Buzzer) Circuit Analysis. Figure 1 shows the schematic diagram of the PWM cooling FAN controller device. The heart of the circuit is an ATTiny13 ...

The Equivalent of LM56 but With an External Thermistor. In Figure 5, we designed an analog version of the LT56, with the limit cycle of temperature control Tlow and Thigh, both determined by two ...
