Proximity sensors are commonly used today alongside Arduino for many applications, ranging from distance measurement, object detection, to heat emission measurement. Hence, picking one that’s easily connectable, accurate, and reliable is very much important for fulfilling your intended usages.<\/p>\n\n\n\n

Sounds like it’s too much to handle? Not to worry, this blog will introduce a SHARP proximity sensor and discuss how to easily connect it with your Arduino for a plethora of applications! <\/p>\n\n\n\n

Alongside the introduction and Arduino guide, I’ll be showcasing some projects you can try as well!<\/p>\n\n\n\n

And yes, for today’s guide, you will not need jumper wires nor breadboard because of the plug and play capability provided by Grove System<\/a> \ud83d\ude42<\/strong><\/p>\n\n\n\n

The Grove – 80cm Infrared Proximity Sensor<\/a><\/strong><\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Based on the SHARP GP2Y0A21, this IR proximity sensor is a popular choice that I’m recommending for anyone that’s looking for accurate distance measuring beyond your alternatives. <\/p>\n\n\n\n

Packed in a small package with low power consumption, this IR proximity sensor allows for continuous distance reading with a range of 10cm to 80cm! <\/p>\n\n\n\n

This sensor is quite small and uses a tiny connector called the Japan Solderless Terminal (JST) connector. These connectors have three wires: Ground, VCC, and Output. Because the sensor fire continuously and don’t need any clock to initiate a reading, it is easy to interface with any microcontroller. for the Seeeduino 4.2<\/a>, the wire converts the 3-wire to 4-wire so that it can be compatible with the twig interface of Grove.<\/p>\n\n\n\n

What makes this an attractive option?<\/strong><\/h4>\n\n\n\n

Small form factor<\/strong><\/p>\n\n\n\n

Built small for seamless applications, you wouldn’t have to worry if it doesn’t fit into the smallest project space you’re working with!<\/p>\n\n\n\n

Ease of Usage with Japanese Solderless Terminal (JST)<\/strong><\/p>\n\n\n\n

Since it uses a tiny connector called the JST, all you need to connect the proximity sensor with is a 3pin JST wire. This eliminates the need for many jumper wires and manually soldering it for pairing purposes!<\/p>\n\n\n\n

Cost-performance ratio<\/strong><\/p>\n\n\n\n

Compared to LIDAR which tends to be on the pricier side, the Grove -80cm Infrared Proximity Sensor offers a good cost-to-performance ratio, achieving a distance measurement range of 10cm to 80cm for only $13.90!<\/p>\n\n\n\n

Grove Interface <\/strong><\/p>\n\n\n\n

Grove? Grove system is Seeed very own initiative, mainly aimed at helping users like yourself to easily use different modules, sensors, and more through our plug and play system! <\/p>\n\n\n\n

We currently already hold more than 200 Grove modules, including other proximity sensor types for you to choose from!<\/p>\n\n\n\n

Don’t believe how easy pairing is made possible with Grove? Below shows a general proximity sensor vs the Grove – 80cm Infrared Sensor: <\/p>\n\n\n\n
