Description

CWX-1-BME280-Kit  STEM SDK IoT (Compact Weather Station IoT Home Automation)

This product is a complete kit of parts

  • CWX-1 PCB (Built and Fully Tested – Latest Version 1.2204-106)
  • BME280 Module (requires to be soldered)
  • Waterproof Enclosure (Clear Plastic Cover)
  • Battery Holder (requires to be soldered)
  • CR123A Lithium Battery
  • USB UART (requires to be soldered)
  • UART Cable (requires to be soldered)
  • Header Pins

 


Powered by a single CR123 Lithium battery (or external 3V3 DC), this CWX-1-BME280-Kit STEM SDK is a Compact Weather Station for IoT Home Automation, providing:

  • Barometric Pressure
  • Temperature
  • Humidity
  • Light Level (Dusk till Dawn, Daylight, Ambient Light, Sunlight etc.)

An example of the output can be seen here  as highlighted below.

 

 

 

 

 

 

 

 

 

 

Based on the industry standard ESP8266 (ESP-12S Series), the SDK includes:

  • BME-280, to provide a low power
    • Barometric Pressure, 300-1100 hPa
    • Temperature, -40 to +85°C
    • Humidity, 0-100% Relative (± 3%)
  • SFH2440, to provide a high linearity Ambient Light Sensor.
    • Spectral range of 400 to 690 nm

 

Connections

The CWX has four headers.

  • BMx Sensor header
  • UART with RTS and DTR (avoids the need to press reset when flashing)
  • SPI (expansion)
  • I2C Plus GP16 or 1-Wire (expansion)

 

Software Code

Arduino IDE based software / firmware code for this CWX ESP project will be provided in our Wiki, to easily get you up and running.  This code connects the CWX to your Wi-Fi and then uploads to a ThingSpeak channel.  FREE ThingSpeak accounts for small non-commercial projects are available (providing up to four channels), so you could have more than one project running at once.

 

MQTT

You may of course use your preferred MQTT Code which connects to other services.

 

Note regarding the UART cable.

CWX-1-BME280-Kit SDK has been designed to flash/program easily by using the RTS and DTR connections on a UART. This enables automatically flashing without pressing/holding any buttons).  Details are in the Wiki.

 

Sensors

This CWX-1 SDK board will work with all three BMx sensors, including the low cost BMP180.  However, in order to get Humidity and better resolution, you require to use the much better BME280 – which is included with our CWX-1-BME280-Kit SDK.

 

 

 

 

 

 

 

 

 

 

 

 

 

Cut-outs

The CWX-1-BME280 PCB has cut-out to allow the BME280 sensor to fit flush and also the light sensor to be swapped facing up (PCB top) or down (PCB bottom).  (Default is up).

 

 

 

 

 

 

Enclosure

The CWX-1-BME280 PCB is designed to fit into a standard 85x58x33mm Waterproof Clear Cover Plastic Enclosure.  This is provided in this kit.

 

Battery Holder

The CR123A Battery Holder is supplied with the SDK but can be optionally soldered as needed.

It has a locating pin, to aid correct fitting.

 

In the Box

CWX-1-BME280-Kit STEM SDK is supplied as a Developer Kit PCB.  SMD Populated and Tested.

You will need to update the firmware with your preferred open source firmware, using a standard UART (3v3).  Working examples of code for ThingSpeak can be found in our Wiki
