Medium Systems Limited, a UK company has released the Mastak, SoMs designed in a mechanical range that allows for indoor air quality monitoring, with a data IoT cloud service, and communications that include NB-IoT, 5G, WiFi, BLE, and LTE-M. The system is a new addition to the air monitoring market place. There have been reports on other air quality monitors in past articles that covered quick start and user experience with Sonoff SC WiFi, vThings WiFi CO2 Monitor, and the ANAVI Gas Detector.
The ecological modules are all compatible and contain processor, peripherals and the sensors for data monitoring and collection, as well as the necessary power electronics. The modules were designed too and allow the user to arrange the systems into custom arrangements and place in unique form factors. There are a number of options also, for even further expandability and functionality. The systems come with the following specs.
- ESP 32 based
- 3G, NB-IoT, LoRa, BLE, Wi-Fi as communications methods
- Set of important sensors
- Low cost
- Low power
- High availability & reliability
- 4x GPIO
- 1x I2C
- 1x SPI
There are several packages and optional arrangements available and there is a screen available for data and GUI presentations. The system is fully customizable from the type of sensors to what modules can be ordered with the units. The base package carries some very good quality and functional sensors for general purpose monitoring in any way the user would like. The following comes in the package –
- Block with GSM slot and following sensors:
- Telaire T6703 – CO2
- BOSCH BME680 – TVOC (Total Volatile Organic Compounds), Temperature. Pressure, and Humidity
- TI OPT3001 – Light
- AD DMP401 – Noise
- Block For Battery
- Durable Plastic Toolbox Case
The base system starts at $229.00, with optional E-Ink Screen ($49.00), Formaldehyde Sensor or Ozone Sensor ($30.00 each – these sensors are not compatible with each other) and a PM1.0, PM2.5, PM5.0 and PM10 Dust Sensor ($47.00) shipping to the USA starts at $20.00. Shipping to other countries was not indicated.
The E-Ink screen is 4.2-inch 400 x 300 px resolution with an embedded controller. Some of the advantages of the screen are ultra-low-power (basically only needs power to refresh) 170ᵒ viewable angles and no backlight.
