Welcome to BurgessWorld Custom Electronics Tindie Store!
Burgessworld Custom Electronics
This board has been modified to include a battery-protection diode. This prevents back-feeding 5v to the batteries if they are installed while the board is connected to a 5V source. The revised board is version 1.21B.
This Arduino-compatible, battery-powered, Wifi-enabled DHT-22 sensor board allows you to easily deploy a remote Temperature and Humidity sensor. Upload data to a free ThingSpeek.com channel, to your ConnectedHome central monitoring station, or to any other location you desire - it is completely up to you!
NOTE: The Sensor Board is fully assembled but the 18650 battery holder has not been attached. This is to allow you to add additional sensors if desired. You will need to mount your own additional sensors (optional), and solder the battery holder onto the board. You can optionally select to have the battery holder mounted and female pin headers installed in Sensor2 and Sensor3 prior to shipping.
Using 2 18650 3.7v batteries (batteries not included), this SMART sensor board can be deployed ANYWHERE. As long as it can connect to Wifi, it can upload temp/humidity data.
There are 2 additional 3-pin sensor ports to allow you to connect additional sensors if you desire. Sensor2 and Sensor3 use the same Arduino pins as the I2C port (A4 & A5),so you can use I2C sensors as well as any 3 or 4 pin sensor you like (a 4-pin sensor would use both ports). VCC jumper allows for 3.3v or 5v sensor voltage supply for maximum flexibility.
On-board DHT-22 sensor measures temperature and humidity with 0.5%C temperature accuracy and 2% humidity accuracy. Fully supported by easy-to-use Arduino library, on Arduino pin D16/A2.
On-board 3.3v Boost regulator provides 800ma and can be shutdown from within your Arduino sketch (pin D3) for Ultra-low power consumption.
(Optional) 5v Boost regulator provides 1.5A from a supply as low as 2.5Vdc, allows the board to run at 5vdc and support 5v sensors.
Monitor battery voltage via dedicated Arduino pin
By adding your own additional sensors, deployment options are limitless.
ARDUINO IDE compatible. Compatible with all Arduino libraries.
Supports up to 3 on-board sensors simultaneously (DHT-22 takes up one port)
Pull-up resistor can be installed on Sensor3 port (4.7k resistor included)
Supports WiFi communications with included ESP8266 modules (ESP-01)
Atmega328-based; fully supported in Arduino IDE for ease of programming (board type UNO/Genuino), 28-PIN DIP IC for easy removal or replacement
Arduino UNO/Genuino bootloader pre-loaded
Flexible power options; can use 2 18650 batteries (parallel only) via the on-board battery holder, or can be power from the 2-pin Molex connector (2.5 to 5Vdc DO NOT EXCEED 5Vdc)
Dedicated Arduino pin for monitoring and reporting battery voltage
On-board red/green LED allows for status signaling
Configurable for ULTRA LOW POWER; can run several months on 2 18650 batteries when properly configured
5-pin Program/Debug port for easy sketch/HEX upload via USB-Serial adapter (optional)
6-pin ICSP connector for uploading Ardunio bootloader or sketches/HEX directly via AVRISP programmer (optional)
3-pin Progam/Debug port for ESP-8266; allows for firmware updates
Flash button for ESP-8266, with slide switch to enable DEBUG mode
See the product page for the various serial programmers I sell for instructions on installing the driver and communicating with the board:

All boards in this store are designed by me and professionally printed in one of several global fabrication shops
All boards are hand-assembled and fully tested
Most projects require some level of soldering - usually minimal skill level required
SMD components on boards will be pre-assembled before shipping unless otherwise stated in the description
Some kits are shipped as board + components only - please read descriptions thouroughly
Certain boards may be available as BOARD-ONLY with parts-list and schematic
PDF of schematic and parts lists are available on-request for most boards
