Applications: air conditioning, central heating, coolers, laboratory, greenhouses, aquariums, ventilation.

A project for automation, hobby and also learning.

Simple and inexpensive project, especially useful for amateur astronomers, which drastically reduces the time to find the desired object in the night sky.

A cute tiny infrared thermometer with -70 to 380 °C temperature range

This device is better than the similar devices made with an Arduino microcontroller board thanks to the stronger microprocessor and the well-made Windows software.

Shield for learning.

Minimalistic board that allows you to quickly and easily utilize a silicon photomultiplier (SiPM) within your other projects. Supports a range of input voltages, has a digital (TTL) pulse output for the registered counts and a direct output for the SiPM pulses for easy expansion.

Hackable, fully open-source gamma-ray spectrometer using a scintillator crystal and popular silicon photomultipliers.

This small project can be interesting for beginners in electronics or robotics.

Discover the DIY Digital Oscilloscope: affordable, easy-to-build, and perfect for hobbyists, students, and professionals.And it also very cheap to build it.

This is a small (17.9 mm x 10.3 mm) breakout board for PixArt's PAA3905 optical flow sensor. It provides X-Y velocity at 126 Hz via Optical Flow and 35 x 35 pixel video camera at 18 Hz. There is a well-commented Arduino sketch showing how to use the device for navigation and frame grabbing. The frame grab rate is significantly improved over its predecessor, making for a practical low-resolution still imaging and video camera capability. Power usage is a modest 3.5 mA and the sensor can move in and out of shutdown mode quickly allowing flexible power management. The light level adjustment is automatic (although can still be done manually), streamlining sensor management. The sensor is smaller than its predecessors, with fewer pins making design and assembly easier. Light level sensitivity extends down to 5 lux. The frame grab occurs at a crisp ~15 Hz (56 milliseconds to complete), allowing low-resolution video imaging using the infrared-sensitive sensor element. Open source design!

Not only make the plants look clean and tidy, but also observe the status of the plants at any time.

Perform infrared remote control decoding

It is a digital multi-gas sensor that facilitates solutions for gas quality in life and can be used in smart homes, HVAC, building automation, etc.

This Ultrasonic Distance Sensor is provides non-contact distance readings from 2cm to 400cm.
