Description
Adjustable detection range, 3cm - 80cm
Small, easy to use/assemble, inexpensive
Useful for robot, interactive media, industrial assembly line, etc
Power supply: 5V
The Gravity Adjustable Infrared Sensor Switch is a set of transmitter and receiver in one of the photoelectric switch sensor. The detection distance can be adjusted according to the demand. The sensor has a detection range of 3-80cm. The DFRobot Adjustable Infrared Sensor Switch is small, easy to use, inexpensive, easy to assemble and can be widely used in robot to avoid obstacles, interactive media, industrial assembly line, and many other occasions. The switching signal output differs in accordance to the obstacles. It remains high when no obstacles and remains low when there are obstacles. There is a bright light behind the probe to detect the scope of 3cm - 80cm.
The sensor is easy to connect and the detection distant adjustment is easy to use. When placing the sensor in a confined spaced, the user needs to calibrate the distance adjustment prior mounting the sensor in the bracket.

Very good
The quality is not the best being there are rough edges in the mold of the plastic. I guess for the price that is what you get. The function of it is very good. It has an adjustable trimpot on the back to dail in exactly where you want it to trigger.

Nice find!
Surprisingly good considering the price. Notes: - Fairly precise adjustment but the min and max ranges tend to vary from one unit to the other. - The min range could be a little shorter. It varies between 1.5 and 3 inches depending on the unit and the nature of the reflective surface. - There is a convenient LED integrated inside the sensor body which helps adjusting the range or debugging for embedded applications. - The plastic threads on the sensor body are pretty fragile. - Some units appear to be sensitive to RF fields. I stuck a bunch of these right next to RFID readers and about half of the sensors would stay on when the RFID readers were active. Moving them away a few cm did the trick.

Belle trouvaille!
Étonnamment bon vu le prix. Remarques: - Réglage assez précis mais les plages min et max ont tendance à varier d’une unité à l’autre. - La plage minimale pourrait être un peu plus courte. Il varie entre 1,5 et 3 pouces en fonction de l'unité et de la nature de la surface réfléchissante. - Une DEL pratique intégrée au corps du capteur facilite le réglage de la plage ou la mise au point pour les applications intégrées. - Les fils en plastique sur le corps du capteur sont assez fragiles. - Certaines unités semblent être sensibles aux champs RF. J'en ai collé plusieurs à côté des lecteurs RFID et environ la moitié des capteurs restaient allumés lorsque les lecteurs RFID étaient actifs. Les éloigner de quelques cm a fait l'affaire.
