ESP32 Weatherstation

ESP32 based Weatherstation Uses attached sensors, remote sensors and Internet weather information to display current weather on a 1.44" TFT display.

Detailed informations about it are on my website

Development platform

PlatformIO

Used hardware

• Elecrow ESP32 WIFI BLE BOARD WROOM
• Elecrow 1.44" TFT display
• Adafruit TSL2561 LUMINOSITY/LUX/LIGHT DIGITAL SENSOR BREAKOUT
• Elecrow DHT11 TEMPERATURE AND HUMIDITY SENSOR
• LDR
• 10k and 2.2k resistor
• ESP8266 security module with PIR, light relay, alarm buzzer and DHT11 temperature and humidity sensor (optional, another DIY project)

SW practices used

• Use of ESP32 HW timer
• Use of SPI (for the TFT display)
• Use of I2C (for the TSL2561 light sensor)
• Use of bit-banging 1 wire interface to DHT11
• Use of ESP32 touch interface
• Use of ESP32 multi tasking
• Use of ArduinoOTA for SW updates
• Use of MQTT for web based information display
• Use of UDP broadcast messaging
• Use of UDP broadcast receiving
• Use of TCP socket server to receive commands
• Use of BLE for sending sensor data
• Use of Bluetooth Serial for debugging
