SMP3011 I2C output pressure sensor
SMP3011 uses metal membrane to isolate oil-filled pressure sensor core. The product has built-in temperature compensation sensor, which can compensate the zero error and temperature drift of sensor signal, sensitivity error, temperature drift and nonlinearity error in real time, and output pressure and temperature data in accordance with the I2C interface protocol.The product is small in size, simple in installation, high in cost performance, accurate and reliable in pressure measurement, and greatly enhances the on-site adaptability of the sensor.
