So … I am dipping my toe into the world of ESP, I have got the following
1 x TEPT4400 Phototransistor
1 x Seeed Studio XIAO ESP32‑C3
1 x 10k resistor
1 x 3.7 V LiPo 500 mAh battery
Now i need to figure out how to connect them all together so i can find out when my boiler relay light from Evohome is turning on.
Can anyone help ?
oh and a load of dupon cables and a breadboard if that helps ?
I have a project similar to yours, the parts are almost here to test.
The only difference is the lipo battery. I will try first plugged to usb and maybe later with battery. Not sure if that is a bit of a challenge because of the c3 and sensor consumption.
That is for initial testing. The final project is better with a proper perfboard and solder.
do you have any wiring diagrams showing how it will be wired up ?
Not yet; probably something similar to this and then esphome:
Or like here (disregard the part about the pir sensor).
so its basically that
Might do it using the breadboard for my first attempt, then i just need to solder 3 points and do the rest on the board with the resistor.
You don’t even need that resistor with tept4400.
I wrote topic about it while ago.
