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.

Ideal for building a car with obstacle detector, light follower.
Includes battery compartment for 4 AA batteries and ignition switch. (batteries not included). 4WD Robot Smart Car Chassis 4x Wheels DIY features:
- Voltage: 3 to 6Vdc
- Speed without load: 100 RPM to 6Vdc
- No-load current: 90mA to 3Vdc - 180mA to 6Vdc
- Dimensions of the wheel: diameter 65mm - width 26 mm
