CWX-1 Schematic CWX-1 PCB Components
The CWX uses a BME280 High Precision Temperature, Humidity and Barometric Pressure Sensor. This digital sensor module being contained on it’s own PCB and interfaces to the standard I2C bus, such as used on most microcontrollers such as ESP8266 series, Arduino boards, Raspberry PI etc. This BME280 module is factory calibrated to provide a high […]
The below RMIS-1 test code example has been provided as a means to learn, develop and evolve. The purpose of this test code is to cycle through the various main functions of the board as part of bring up testing. This example code has been developed for a test Solar/Wind/Battery/UPS project – which is very […]

The CWX 1 – STEM SDK IoT (Compact Weather Station),, includes on-board digital temperature sensor, however it would be great to also add an external temperature sensor, such on a greenhouse or room. Using the I2C connector and sharing the I2C bus, it is very easy to add one to test, or more, one-wire digital […]
RMIS (Remote Monitoring IoT System), includes on-board digital temperature sensor, MCP9808 (located next to the ACS712 current monitors). However it would be great to also add an external temperature sensor, such on a battery or heatsink. Using the I2C connector and sharing the I2C bus, it is very easy to add one to test, or […]
RMIS (Remote Monitoring IoT System) features four independent and isolated channels, each of which can monitor both DC voltage and current. When all four input channels are used, it would result in eight readings (4 x current and 4 x voltages), being provided in real-time. The current measured is also positive and negative, so RMIS […]
