Since we live in big polluted cities the air quality is on a very poor level. But, the problem is not only connected to the big cities - even smaller cities and villages may suffer from air pollution. That's why we've created this little project to let you build your own Particulate Matter monitoring station and use our open-source software so you could monitor the air quality in your place of living.
Let's live healthier life and start measuring the air quality and filtering it if necessary.

- PlanTower PMS7003 ~$26
- ICD10 adapter with 10 pins(1.27 mm) to 6 pins (2.54 mm) (also called
G7 switch) ~$2 - UART to USB adapter:
- Female-Female wires 5 items (required for PL2303 otherwise optional since FT232 can be bought with wires already included) ~$1-2
- USB OTG cable ~$1
Caution! Connectivity to the sensor over Bluetooth is currently only supported by the desktop application ran on macOS.
Caution! If you want to connect from Apple iPhone or Apple Watch - please see Low Energy version (below)
- PlanTower PMS7003 ~$26
- ICD10 adapter with 10 pins(1.27 mm) to 6 pins (2.54 mm) (also called
G7 switch) ~$2 - Female-Female wires 5 items ~$1-2
- Bluetooth UART HC-06 ~$7
- recycled old USB cable to provide power to Sensor and Bluetooth tandem
Caution! Connectivity to the sensor over Bluetooth LE is currently only tested on the iOS application running on iPhone or Apple Watch. Multi-platform desktop support not planned in near feature.
- PlanTower PMS7003 ~$26
- ICD10 adapter with 10 pins(1.27 mm) to 6 pins (2.54 mm) (also called
G7 switch) ~$2 - Bluetooth Low Energy UART HC-08 (includes wires) ~$7
- recycled old USB cable to provide power to Sensor and Bluetooth tandem
You may want to use the following rebate coupon: A9XS1FPF on purchases made on KAMAMI.COM or KAMAMI.PL to get 5% OFF on orders which include PMS7003 (to be used only once for each buyer).
- Connect the PlanTower device with ICD10 adapter (
like on photo below).
Caution! The pins on the PlanTower device are located in the top right corner. Numeration starts from the right top corner (1) and ends in the left bottom corner (10).
- Connect IDC10 adapter (bigger pins 😄) to the UART-USB adapter. Wire connections are presented in a table below
Caution! The adapter must have a separate VCC pin for 5V or a switch between 3.3V and 5V since the PlanTower device works on 5V voltage.
| ICD10 adapter | UART-USB adapter |
|---|---|
| VCC (5V) | VCC (5V) |
| GND | GND |
| RX | TXD |
| TXD | RXD |
- Connect the UART-USB adapter with a USB cable to your computer
Caution! Refer to this section for remarks regarding your platform
- Start the application and check the air quality of your environment 😄
-
Follow 1-3 steps of USB instruction above, but use your Bluetooth or Bluetooth LE module instead of UART-USB adapter
-
Cut off any old USB cable
-
Connect the power (5V) from USB cable or socket to Vcc and GND (2 most outside pins of USB plug, usually red 5V cable and black GND). You may need to shortcircuit data pin/wires (2 center pins) or connect them via ~200ohm resistor in order to be recognized by charger. Details can be found here.
-
4x M3 x 25 machine screws with nuts are required to assemble the enclosure
or
or for FT232 usb-uart adapter
Suggested printing parameters:
- Infill: 20%
- Resolution: 0.2
- Supports: No
Caution! Make sure the soldered ends of the USB-UART pins (at the bottom of the adapter) are properly insulated from the sensor's metal case! Some adapters have them so long that they become too close to the sensor and may short-circuit the adapter. It's best to sand them off and use insulation tape.
