Pressure Sensors
YRD04-YLC
Digital Pressure Sensor
Product Overview
The YRD04-YLC digital pressure sensor uses a highly integrated microprocessor-based circuit to acquire, process and output pressure and temperature via an I2C interface, converting analog signals to precise digital values. With 3.3 V supply, ultra-low standby current (<5 μA) and anti-interference design, it is widely used in IoT, defense, petrochemical, hydrology and 5G industries.
