Project description
Designed for use with either Sonoff/Tasmota (https://github.com/arendst/Sonoff-Tasmota) or ST_Anything (https://github.com/DanielOgorchock/ST_Anything) Uses a AC/DC 5v converter (HLK-5M05). 5v to 3.3v regulator(AMS1117) to power an ESP01 module (recommend 1Mb version). 5V SPDT Songle relay (SRD-05VDC-SL-C) for switching with GPIO0 GPIO0 requires to be pulled high for normal booting so the relay is set to turn on immediately with power applied and must be set low to turn off. GPIO2 is availalbe with the 3 pin header with 3.3v and Gnd. It is set up for easily plugging in a DS18B20 temperature sensor. Or can be used for any other sensor or for manual button input.
