HC SR04 Ultrasonic Sensor Module

The HC‑SR04 ultrasonic sensor module supplied by Js Power Control Systems is a compact transducer that emits 40 kHz sound pulses and receives the echo to calculate distance. It operates from a +5 V DC supply and provides a digital echo pulse whose width corresponds to the measured range. Theoretical measuring distance spans from 2 cm up to 450 cm, while practical reliable measurement is limited to 2 cm-80 cm. The device advertises an accuracy of +/-3 mm under standard laboratory conditions. Its measuring angle is approximately 15 degrees.

In most hobbyist and industrial projects the HC‑SR04 is paired with micro‑controller boards such as Arduino or ESP32, using the trigger‑echo interface. Typical specifications include a supply voltage range of 3.3-5 V, a current consumption around 15 mA during operation, and an operating temperature window of -20 °C to +70 °C. The module’s output is a TTL‑level pulse compatible with standard digital inputs, and it is usually mounted on a PCB with three mounting holes spaced 16 mm apart. Standard packaging for bulk orders is anti‑static poly‑bagged units of 100 pieces.

Manufacturers of robotics, level‑sensing tanks, and proximity alarms frequently source the HC‑SR04 for distance‑measurement tasks. Importers typically request bulk quantities packaged in sealed poly‑bags and negotiate FOB terms from the Faridabad port of entry. Js Power Control Systems does not list a minimum order quantity, so buyers should confirm the desired volume and any required custom testing directly with the supplier.

Js Power Control Systems is located at Plot No -230/1, Panch Peer Gali, Sant Nagar, Old Faridabad, Haryana 121002, India. The supplier holds a harbour trust tier on the platform but currently shows a 0.00% response rate and no recorded average response time, indicating that enquiries may require follow‑up. The company lists its core activity as the supply of electronic components such as ultrasonic sensor modules.

The listing does not provide details on production capacity, certifications, or client references, so importers should request documentation that confirms conformity to relevant standards before placing orders. Js Power Control Systems offers the HC‑SR04 module without a stated minimum order quantity, allowing flexibility for small or large purchases depending on buyer needs.
