Description
MEGA 2560 Board compatible with Arduino + DHT11 Humidity and Temperature Sensor Module
The MEGA 2560 R3 CH340G Board is a microcontroller board base on the ATmega2560. It has a USB host interface to connect with Android-based phones, based on the MAX3421e IC.
The At Mega2560 has 54 digital input/output pins (of which 15 can be used as PWM outputs); 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator; a USB connection, a power jack, an ICSP header, and a reset button. The MEGA ADK is based on the Mega 2560. Similar to the Mega 2560 and Uno, it features an ATmega8U2 program as a USB-to-serial converter. Revision 3 of the Mega ADK board has a resistor pulling the 8U2 HWB line to the ground, making it easier to put into DFU(Device Firmware Upgrade) mode.
The DHT11 Humidity and Temperature Sensor Module is capable of sensing both temperatures as well as humidity. This makes it ideal for projects as well as automation. The board is also equipped with a high-performance 8-Bit microcontroller connected to the DHT11 sensor module.
The output of the DHT11 Temperature Sensor Module is in the form of a digital signal on a single data pin. The sensing update frequency is to be measured every 2sec (0.5Hz). The DHT11 Sensor Module can be interfaced with any microcontroller like Arduino, Raspberry Pi, etc. This Sensor module integrates the DHT11 sensor and other required components on a small PCB.
NEW FEATURES OF THE MEGA2560 R3 BOARD
-
The Mega2560 R3 board features a 1.0 pinout with an added SDA and SCL pins near the AREF pin. It also features two new pins located near the RESET pin. They allow mega2560 shields to adapt to the voltage provided by the board.
-
The At Mega2560 development board also features a stronger RESET circuit.
