Maker André Costa has designed a provider board for the Raspberry Pi Pico W microcontroller board, turning it into an Web of Issues (IoT) host for a Plantower PMS5003 and elective secondary Qwiic/STEMMA QT sensor: the Pico W Air.

“The Pico W Air is a good board if you wish to get into atmosphere information logging,” Costa claims of his newest design. “It comes with a connection for a [Plantower] PMS5003 particulate matter sensor and Qwiic/[STEMMA] QT connector that permits you to join any Qwiic/[STEMMA] QT (I2C) sensor. All powered by the wonderful Raspberry Pi Pico W.”

The provider board comes with a Raspberry Pi Pico W surface-mounted and already loaded with a CircuitPython firmware. The Plantower PMS5003 sensor, the board’s major information supply, connects over a solder-free cable, whereas a secondary sensor could be added utilizing the Qwiic/STEMMA QT connector — and there are 5 general-purpose enter/output (GPIO) pins, together with one analog enter, introduced out to an unpopulated 0.1″ pin header should you want extra.

Elsewhere on the board are pink and inexperienced LEDs, for what Costa calls “standing or different blinking enterprise,” and a footprint for an elective reset button. The firmware comes with a built-in internet server with JSON utility programming interface (API) and an MQTT consumer, suitable with House Assistant, Node-RED, or different MQTT brokers.

The supply code for the challenge has been revealed to GitHub underneath the permissive MIT license, whereas the boards are listed on the DPHacks Tindie retailer for $11.50 together with the Raspberry Pi Pico W — although, on the time of writing, have been displaying as out-of-stock.
