Stop Theft With a Beam of Invisible Light

Have you ever left your garage door open over night? If you're not careful, you might find some things missing in the morning, or wake up to a home invasion. The best case is that you may have a loud knock in the middle of the night from a police officer or neighbor, reminding you to close your garage door.

We developed the Proximity Sensor specifically to remind you when you've left a door open, to keep you and your property safe.

Highly Sensitive and Selective

The sensor will detect doors, gates, people, pets or other objects in its field of view. The distance depends on the size, color and surface finish of the object that you are trying to detect. For example: it can detect your hand at about 30cm (12 in), and detect a white surface or door at about 1 meter of range.

The IR sensor emits an invisible infrared beam of modulated light. It detects this light as it bounces back from objects. Its internal filter rejects visible light, so it will still work in full sunlight.

Cool Design

The case is 3D printed with transparent PLA plastic, to reveal the internal indicator LED. The result is unexpected and stunning. The LED looks like a "cat eye", because of the refraction pattern of the light through the case. This LED turns on, when no objects are detected.

The case is water resistant. We recommend that it not be directly subjected to rain. If placing this outside, make sure that it is under something to protect it.

Easily Mounted

The sensor can be placed anywhere. It comes with an adhesive tape on the back side. Merely peal off the cover on the tape and stick it to any surface.

Simple Analog Interface

The proximity sensor will interface to nearly any other device. It consists of only 3 wires: power, ground and out. The output is 0V when it detects an object, and 3V when it can't see anything.

Vegetronix Modular Building Blocks

We provide modular building blocks that you combine to create garden, home and office automation systems. With these building blocks and the proximity sensor, you can create systems that will monitor all of your doors and gates, and return status alerts through texts and emails.

We recommend using our WiFi Sensor Hub with the proximity sensor to make door and gate alert systems. The sensor hub will periodically turn on the sensor, and send an update to a cloud site, which can in turn send you a text or email message. We recommend using our partner sight for this purpose.

The sensor hub can be battery operated. It will only power the IR proximity sensor, when taking a sample to conserve battery power.

Proximity Sensor Quick Setup Guide

It's best to test out your sensor before you install it into a system.

Hook it up to a 9V battery or power supply. The red wire goes to the positive lead of the battery. The bare lead goes to the negative lead of the battery. Leave the black wire unconnected.

Once power is applied, point the proximity sensor away from any objects or walls. It should be at least 1 meter or more away. The green LED will light. Now place your hand in front of the sensor. The LED will turn off, indicating that it has detected an object. You have now verified that your sensor is working.

You can now hook your device into another system. For example, you could connect it to one of our WiFi Sensor Hubs to connect it to the Internet, or one of our relay boards to sound an alarm, or cause some other action.
