The circuit and PCB have been produced and tested and basic code is available on github. See the project site on hackaday.io for more information about the project.
WX station using 8266 E12 with DHT22, BMP280, and ADS1115 (for wind speed, wind direction, light level sensor, and battery voltage.

Still working on it.. All data is raw and is interpreted in php for web.
Home air monitor is based on the development board NodeMCU (CP2102 version). It includes a temperature sensor - ds18b20, a humidity sensor - HTU21D, a carbon dioxide sensor MNH-Z19. It is also possible to connect one more i2c sensor and a radio module to 433 MHz.
Solar system power for esp8266 device like weather sensor. You need 5V 0.15W solar panel and small li-po battery for example 200mAh. Zener diode stabilizes voltage on 4.3, schottky diode give 0.15-0.2V voltage drop because 4.3V is too much for li-ion battery and prevents lekage current from battery. You can use panel also like binary(0/1) light sensor.
Keep It Simple Stupid
Not tested yet.
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
An IoT board around ESP-12S module (with ESP8266) powered by a 9V-28V DC jack, with 3 signalling WS2812 LEDs, 2 buttons, an OLED display, a beeper and a temperature & humidity senzor. The board is meant to act as a hub and connect to other devices with more sensors, or as a driver for an external device.
