Makers and developers that are looking to carry out or create projects for environmental monitoring may be interested to know that the Arduino compatible EnviroDIY Mayfly Data logger board is now available to purchase directly from Amazon priced at $60.
The Mayfly Data logger is a fully programmable microprocessor board which is fully compatible with the Arduino IDE and is equipped with a Atmega 1284p processor supported by 128K flash memory and 16K RAM.
Other features of the board include 24 digital I/O pins, and 8 analog pins, plus a 4-channel 16-bit analog-to-digital converter, realtime Clock chip, microSD card slot, Bee RF module socket, and solar battery charging capability. Its creators explain more :
A powerful, user-programmable microprocessor board that is fully compatible with the Arduino IDE software. It features the ATmega1284p processor, which is much more powerful than the 328p chip found on most other Arduino boards. It has 4 times more flash memory for sketches, 8 times more RAM, and almost twice as many input pins.
The memory card socket, RTC, and solar charging features make it very easy to use this board for data logging and low-power operation. But it can also be used by itself, or with a wide variety of devices and accessories. It can be powered by a 3.7v lithium battery (not supplied) or through the microUSB port. Programming can be done through the microUSB port (cable not supplied) or via the FTDI header. A 6-pin header adapter is included for attaching your FTDI cable or board (not supplied).
You will need a CR1220 button cell lithium battery (not supplied) in order for the RTC to retain the time after the power has been removed. More information and tutorials for the board can be found on the EnviroDIY website.
