ESP32 weather station

Weather station

Another ESP32 based weather station that retrieves weather data from OpenWeatherMap via WiFi and display the infor on a 3.2″ Nextion Touch Display. It also uses the BME280 sensor for measuring weather data locally. The display is refreshed every two seconds and the weather forecast is made every hour.

ESP32 BLE/WiFi development board

ESP32 development board

We have added a new IoT product to our Tindie store. It is a rapid prototyping and development board for the powerful ESP32 WiFi/BLE module. It is targeted toward rapid development of a wide variety of IoT applications, supporting both WiFi and Bluetooth connectivities. The development board breaks out all the module’s pins to 0.1″ headers and provides a CP2102 USB-TTL serial adapter on board for easy programming. The board also features on-board power supply regulator and an integrated LiPo Battery Charger. ESP-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor

ESP32 based IoT 4WD robot platform

Wifi/BLE enabled 4WD robot platform

Stefan designed an IoT enabled, compact and modular, 4-wheel drive robot platform powered by ESP32. It is controllable over WiFi and BLE. As controller board an ESP32 Thing board is used this can be programmed by the Arduino IDE and allows even OTA updates. It isn’t the cheapest but offers a compact size and includes a LiPo charging capability (Which I managed to blow off by attaching the LiPo in reverse polarity L). As sensors the robot contain a BN0 055 absolute orientation sensor, a rotation encoder for both sides, four proximity sensors in the bottom (line follower, gap detection) and

ESP8266/ESP32 electronic sticky note using e-paper display


E-paper displays are new innovative commercial displays that resembles ink on paper, requires ultra-low power, and can retain the image displayed even in the absence of power. Frank Buss‘ entry to 2017 Hackaday Prize contest is a solar-powered e-Paper display driven by ESP32/ESP8266 and a sticky magnet on back that can be used as a sticky note on a fridge to display important information over WiFi. Frank writes, The amazing thing about ePapers is that the image lasts without power forever (I tested it for months), and the contrast is very good. The idea is to build a small device
