Features: It has both waterproof and pressure-sensitive functions.When the sensor senses the external pressure,the sensor resistance changes. The module is compatible with various MCU control boards,such as Series MCU.The module contains 2 interfaces for you to choose from.One is the anti reverse connection white terminal with a spacing of 2.54mm. The sensor module is based on a new pressure-sensitive material and a comfortable Young's modulu ultra-thin film substrate. We use the circuit to convert the pressure signal sensed by the sensor into the electrical signal output with corresponding change intensity.In this way,we can get the pressure change by detecting the change of electrical signal. When in use,we can stack a sensor expansion board on the single chip microcomputer.The module is connected with its own wire,and then connected to the sensor expansion board,which is simple and convenient.The other is the rows pin interface with a spacing of 2.54mm,which can be directly connected to the single chip microcomputer by using the male to female line. brand new and high quality Package Includes: 1 x Pressure Module Specifications: Conductor length:200mm Working voltage:DC 3.3-5v Interface:anti reverse connection interface pin arrangement interface Size of locating hole:3mm in diameter Control signal:analog signal Measuring range:0-5kg Thickness:0.3mm Response point:150g Repeatability:
