Infrared human presence sensor, adjustable sensitivity and delay (0.3sec - 10 min), operating voltage 5-20V, output level 3.3V high, 0V low, detection range up to 7m (cone angle <120°), working temperature -15°C to 70°C.
Infrared obstacle avoidance sensor is used for smart robot cars, for collision avoidance and line following. Adjustable 2-30 cm range, 3.3 and 5 V logic level.
The sensor contains a very tiny laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the laser light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Range is roughly 50 to 1200 mm, and it also includes a lux sensor.
Simple Time-of-Flight laser ranging sensor, range up to 2 m (depending on light intensity and object reflectance), 1 mm resolution, +/-3-10% accuracy, I2C communication, working voltage 2.6-5.5 V, size 25x12.2 mm.
