Wallmount touch LED light with temperature and humidity sensor

thingiverse

Human: There's nothing more frustrating than getting woken up by the bright bathroom light at night.\r\nSolution: I wanted to create something practical that would also cover a hole in the wall originally intended for a switch.\r\nI used some breadboard, a voltage regulator or DC step-down module (I chose an LD29150DT50R), an ESP8266 (Wemos D1 Pro) module, a TTP223 touch sensor module, an SHT21 temperature and humidity sensor module, two LED strips approximately 40 cm in length, and two N-FETs (IRLB3034).\r\n\r\n!!! Important Notice !!!\r\nThis PCB is designed to operate on 12 V DC. I have a small power supply that converts 230 V AC to 12 V DC in the hallway.\r\n!!! Important Notice !!!\r\n\r\nWhy two FETs? So I can control each strip individually because I want to (Tasmota's PWM causes flickering, so I used two channels to reduce the flicker. Now that I think about it, the FETs may be causing the flicker).\r\nTo minimize ghost switching of the TTP223, I soldered a 10 uF and a 100 nF capacitor between VCC and GND on the module.\r\nI used thin wire for the "antenna" of the TTP223 to ensure it works from about 5 cm away.\r\n\r\nThe schematics should be good enough (and accurate), I made this one after quite a few years. Time to get back in shape.\r\n\r\nShort demo video: https://www.youtube.com/watch?v=2-0Jv6-taZg
