Product Description

ESPEnvi - Environment sensors development board

The ESPEnvi or ESPEnvironmental is an ESP12F based developer board, especially for the easy entry into the world of IoT. 

The board offers a wide range of possible uses for makers, hobbyists and engineers, such as use as a weather station, gas meter, mold preventer, garden shed monitoring and much more ...


It offers the following options in use:

  • measurement of temperature (° C) and humidity (%)
  • measurement of ambient gases in ppm
  • setup and / or connection to a network
  • variable voltage supply from 3V to 11V via Micro USB (cable not included)
  • programming via FTDI chip (not included)


The microprocessor – ESP12F:

  • smallest available 802.11b/g/n Wi-Fi SOC module
  • very low power 32-bit CPU with up to 160MHz clock speed
  • built-in 10bit high precision ADC
  • deep sleep current as low as 0.02mA
  • UART baud rate up to 4Mbps
  • possibility to include AT commands
  • programmable via FTDI interface and push buttons on the surface


The included Gas Sensor – MQ-2:

  • sensors conductivity is much higher when the gas concentration rises
  • can be used as: 

* Domestic gas leakage detector

* Industrial Combustible gas detector

* Portable gas detector

  • Good sensitivity to combustible gas in wide range /high sensitivity to LPG, Propane and Hydrogen / long life and low cost


The temperature and humidity sensor – HDC1080:

  • relative humidity accuracy ±2% 
  • temperature accuracy ±0.2°C
  • 14 Bit measurement resolution
  • 100nA sleep mode current
  • I2C Interface 


Programming concerns

  • Arduino IDE
  • Library → HDC1080
  • Gas Sensor is connected to Pin ADC (analogue output)
  • Pinout Diagram ESP12F

(The case is not included.)


Possible projects:

  • weather Station with data transfer to Google Firebase
  • gas meter
  • unit to measure temperature and relative humidity → prevent mold
  • garden shed monitor
