Esp32 Optocoupler at Rhonda Tabor blog

Esp32 Optocoupler. Ground the led side of the optocoupler to the alarm circuit ground. This tutorial will discuss how to design a relay circuit diagram for any dc or ac loads. The voltage on the pin of the esp 32 shows 3.3v. Ground the transistor side of your optocoupler to the microcontroller ground. The max voltage of the 4n25 shown on the data. I2c universal mosfet 2a fused ac/dc optocoupler board for esp32 / arduino. I'm looking to detect hvac thermostat calls using esp32 gpio inputs. How to design a relay circuit for arduino and esp32. I have a project with a 4 module optocoupler relay, controlled by an esp32 arduino. I wired the project following the instructions to isolate the esp32 mcu and the relay, powering. A typical example is a digital 24v signal of an industrial sensor that has to be read by an esp32 microcontroller. I am intending to use the output from an esp 32 to the input of a 4n25 optoisolator. 16 channels, toshiba photorelay 100v no. I have a total of six inputs (two compressor speeds, blower, reversing valve, and two aux heat levels).
