Shelly 2.5 is a universal smarthome relay enabled to work with all the key smart home systems, including Google Home and Amazon Alexa, as well as an original Shelly solution Shelly Cloud. In contrast to Shelly 1, it can control 2 electrical circuits (up to 2,3 kW each)

The optical module sensor (reflective) with comparator LM393, which detects obstacles with high precision.
The ideal obstacle detection detector for the installation of smart robots.
TCRT5000 - reflective optical sensor that has a compact construction where the light emitter and receiver are placed in the same direction to detect the presence of a object using infrared reflection on the object.
The working wavelength is 950nm.
The transmitter is infrared LED and the phototransistor receiver.
By using LM393 comparator the module has a binary output (D0) that is at level 1 (object is detected).
The sensor allows the detection of an object at a distance of up to 12 mm.
