Sensor Module Pack: Four US-100 Ultrasonic Distance Sensors with Temperature Compensation - What it is: Four compact ultrasonic distance sensors with temperature compensation, designed to measure distance within their specified range. - Voltage and compatibility: Operates from 2.4–5V; compatible with most 3.3–5V microcontrollers (Arduino, ESP32, Raspberry Pi via appropriate interfaces). - Performance: Induction angle under 15° for focused beams; static current less than 2 mA; temperature compensation improves accuracy across ambient temperatures. - Size and build: Compact modules suitable for mounting in tight spaces on robots or automation gear. - Use cases: Obstacle avoidance in mobile robots; distance sensing and mapping in automation lines; proximity monitoring for safety fences or storage bins. - Package and flexibility: Includes four independent sensors for parallel measurements or redundancy; each module can be used individually or as a four-sensor array. - Setup: Simple wiring with common interfaces reduces integration effort.
