Other key parts include the TTGO-T-Display. By type, the board carries 3 capacitors, 2 transistors, 2 connectors, 2 resistors and 1 IC.
It belongs with the sensors, iot & wireless and displays & leds designs in this gallery.
From the project
ESP32 Air Quality Sensor with PMSA003 + BME680 and 1.14" LCD
Air quality sensor integration board that couples together the following modules:
- ESP32 TTGO T-Display module - PMSA003 module - BME680 CJMCU module
I use this to track the AQI in my home. This sensor measures within 1% of 3x different PurpleAir sensors scattered around my neighborhood. The PMSA003 particulate air sensor module in this build should be an improved version the PMS5003 found in the PurpleAir sensors.
