IR Distance Range Sensor Sharp GP2Y0A02YK0F (20cm-150cm)

Description:

Infrared proximity sensor made by Sharp. Part #GP2Y0A02YK0F has an analog output that varies from 2.8V at 15cm to 0.4V at 150cm with a supply voltage between 4.5 and 5.5VDC. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.

This sensor is great for sensing objects up to 1.5 meters away!

Features:

• Operating voltage: 4.5 V to 5.5 V
• Average current consumption: 33 mA (note: this sensor draws current in large, short bursts, and the manufacturer recommends putting a 10 µF capacitor or larger across power and ground close to the sensor to stabilize the power supply line)
• Distance measuring range: 20 cm to 150 cm (8″ to 60″)
• Output type: analog voltage
• Output voltage differential over distance range: 2.05 V (typical)
• Update period: 38 ± 10 ms
• Size: 44.5 mm × 18.9 mm × 21.6 mm (1.75″ × 0.75″ × 0.85″)
• Weight: 5 g (0.18 oz)
