About Mastak

the ecological sensor kit Module is a range -mechanically-compatible System on Modules (SoMs) containing processor, peripherals, set of sensors and supporting power circuitry. These modules allow a designer to leverage the ecological sensor kit hardware and software stack in their own custom systems and form factors. In addition these modules have extra IO interfaces over and above, opening up more options for the designer.

Design your own Indoor air quality sensor kit and service and implement it into:

• household electronic devices;
• furniture and interior items;
• creating electronic devices with original design under the own brand name.

Сonnect Eco sensor kit with various devices for transmitting and using data from sensors.
