TinyESP without OLED
5V micro USB power input or Li-Po baterry power with charging feature 1 relay with terminals: NO,C,NC 1 wire bus for DS18B20 temperature sensors analog input for voltage or baterry measurement up to 5V universal logical or pusle input I2C bus for different sensors on 2 connectors: 1.25mm (support tiny BME280) or 2.0mm button: for display wake up, settings reset to default or during upload firmware by console serial port UART (3,3V voltage) – for firmware upload (if no firmware) or for serial sensors like CO2 2.0mm terminal for own usage (2 GPIO’s shared with buzzer and IRLED) terminal socket 2.54mm to OLED 0.96″ display buzzer for generating sound ,can be used as acustic notice IRDA – transmitting IRLED to send infrared commands to differents home apliances.
enviromental measurements (temperature, humidity, PM, CO2, lightening) voltage measurement 0-5V logical notification 0-1 (joining to ground) cyclic sending data to own server (Domoticz, OpenHAB or other) or to cloud like mqtt.ats.pl device control by relay: gates, heating or IR diode: TV’s, air conditioning. buzzer or relay switched on by http command from other network device like Lan Controller simple automatic function triggered by sensor reading sending notification by mail or by playing by buzzer display current sensor data on OLED simple distance measurement support RFID readers and many more…
