The AZEnvy or AZ-Environmental 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
