This powerful, flexible sensor board is based on the Arduino Nano micro-controller and includes an ESP-01 ESP8266 Wifi module and also supports the NRF24L01+ 2.4Gzh radio transceiver.

It supports multiple sensors, including almost any I2C sensor via the break-out port.

It can be configured with an optional on-board CCS811 Air Quality sensor DATASHEET for monitoring VOC and eCOT along with a BME280 DATASHEET add-on board for monitoring Temperature, Humidity, and Barometric pressure sensor. When used together, the two make for a fully-functional home environmental monitoring system.

The board also supports up to 2 SR-HC04 or US-100 Ultrasonic distance sensors AND up to 2 HC-SR501 Passive infrared motion sensors.

The system is built around an Arduino Nano so it is 100% Arduino IDE compatible and can be programmed from a USB port via the included mini-USB cable.

The system has been designed to shore up the Nano's shortcomings and add additional functionality.

Because the board supports both ESP8266 and NRF24L01 modules at the same time, it can be used to bridge 2.4Ghz radio and Wifi networks.

FEATURES

• An on-board 3.3v voltage regulator capable of delivering 600ma of current;
• Nano 5v voltage regulator capable of delivering 500ma of current;
• Standard 2.1mm barrel jack along with a reverse-voltage protection diode and a ferrite bead allow for the board to powered from external power up to 12V;
• MicroSD card reader allows for saving data locally or loading configuration info;
• ESP8266 allows for wireless network access
• 3-pin header with RUN/PROGRAM switch allows for flashing new firmware to ES8266 of monitoring communications with Nano for debugging purposes;
• Tactile switch to initiate flash mode on ESP8266
• Optional NRF24l01 module allows for interfacing with existing 2.4gzh wireless home monitoring systems;
• 3-pin DEBUG header allows for monitoring Nano serial port via a USB-Serial adapter;
• Optional on-board CCS811 Air Quality sensor, WAKE and RESET can be jumpered to Nano pins for full-functionality (uses PIR pins)
• Optional remote BME280 temp/humidity/pressure sensor with 12-inch cable
• Dedicated 4-pin I2C breakout header allows for connecting virtually any I2C device for monitoring or communications;
• 2 dedicated SR-HC04/US-100 distance sensor ports;
• 2 dedicated HC-SR501 Passive Infrared ports;
• 2 12-bit ADC pins paired with GND pins to allow for ADC functions;
• 6-pin ICSP interface allows for burning new bootloader to Nano with a AVR programmer
• 4 3mm mounting holes for securing the board to your project
• All pins, ports, and communications channels clearly marked for easy of use;

Supports standard Arduino libraries for all sensors and modules to take the guess work out of designing your sensor solution.

This board can be ordered fully-assembled or as a kit for self assembly. If ordered as a kit, all SMD components will be pre-installed and you will need to solder on the Nano and all headers and connectors.

NOTE: The CCS811 is a high-quality, high-precision Gas/Air Quality sensor. When used for the first time it requires a 48-hour burn-in period. Thereafter, it requires a 20-minute self-calibration period on startup. See DATASHEET and applications notes for more information.
