Product Introduction
The SPB11 thin film pressure sensor is a membrane switch used for real-time response of instant pressure. It has the advantages of low trigger point, sensitive response and high resolution.
The size, shape, detection range and other parameters of the sensor can be customized. The circuit uses pull-up or pull-down resistors to achieve high-low level signal switch, and can be directly connected to the main chip GPIO or INT pin input for application.
Main Application
Electric blowpipe It is mainly used in products and scenaries such as electric blowpipes, small household appliances, smart door locks, lamps, smart homes, etc.
Sensor Characteristics
Designed and developed specifically for control switches. It have characteristics such as low cost, lightweight; high temperature resistance, water resistance, fast response time, long life time, low power consumption (high impedance when no force is applied). While the pressure increases and reaches the threshold pressure, the switch on-resistance is close to 0Ω.
