This is a major upgrade to my Battery-Powered Wifi Temp/humidity Sensor found HERE.
The layout has changed but it is compatible with your existing sketches.
This Arduino-compatible, battery-powered, Wifi-enabled DHT-22 sensor board allows you to easily deploy a remote Temperature and Humidity sensor along with additional sensors of your choice.
You can now OPTIONALLY replace the DHT-22 sensor with an HC-SR04 Ultrasonic Range sensor. A male header will be installed in Sensor port 1 in-place of the DHT-22 and a 12-inch, 4-pin cable is provided.
Upload data to a free ThingSpeek.com channel, send it to your ConnectedHome central monitoring station, log it locally with the NEW OPTIONAL MicroSD card module, or send it to any other location you desire - it is completely up to you!
Using 2 18650 3.7v batteries in parallel (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.
NOTE: This Sensor Board comes 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 elect to have the battery holder mounted and female pin headers installed in Sensor2 and Sensor3 prior to shipping.
There are 2 additional 3-pin sensor ports to allow you to connect additional sensors if you desire. Sensor2 and Sensor3 use Arduino pins D10 and A1.
There is a dedicated I2C port, so you can connect I2C sensors or control I2C devices.
There is a dedicated SPI port, which is PIN-COMPATIBLE with the MicroSD card module I sell in my store. This allows you to log data locally in areas where you don't have a Wifi connection.
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.
Battery voltage is connected to Arduino pin A0 through a voltage divider, allowing you to monitor battery voltage.
By adding your own additional sensors, deployment options are limitless.
100% ARDUINO IDE compatible. Compatible with all Arduino libraries.
Supports up to 3 on-board sensors simultaneously (DHT-22 takes up one port) + I2C and SPI sensors
Pull-up resistor can be installed for Sensor2 and Sensor3 (through-hole resistors not 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 (A0)
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

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
