Highquality materials The flexible film pressure sensor is made of polyester film with excellent mechanical properties, highconductivity materials, and nanoscale pressuresensitive material. The top layer is a flexible film with a pressuresensitive composite the bottom layer is a flexible film with printed conductive traces. Ideal for Arduino prototyping, sleep monitoring, smart footwear, pressure switches, counters, medical devices, robotics, and industrial process control.Durable stable Tested with a 2 kg weight impact, rated for millions of cycles. Low drift and tight tolerance individual sensor resistance 3. Activation time 0.01 s response time 10 ms. Trigger force 20 g. Default trigger condition sensor resistance 200 k. Operating temperature 40 C to 85 C.Packing Each plastic box contains 4 film pressure sensors. Thickness 0.4 mm. Sensing range 20 g2 kg. Built on a flexible PET substrate for conformal mounting on curved or flat surfaces without loss of sensitivity. Sensors are used in series with a fixed resistor measure the voltage across the fixed resistor Vout Vcc R0 R0 RS As a rule, choose the fixed resistor R0 13 to 12 of the sensors application resistance range. Selecting an appropriate fixed resistor can make pressure vs. output voltage approximately linear over a certain pressure range.Usage instructions Install the sensor on a solid, flat, and smooth surface. Protect it from sharp objects. Use a cover layer polycarbonate film or elastomer for protection. The sensor material is not recommended for direct liquid contact and requires waterproofing if exposed. Overload will not permanently damage the sensor it will return to normal operation after the load is removed. For designs involving motion, use soft rubber or a spring as part of the trigger mechanism.Pressurethreshold switch application A typical threshold switch circuit uses a Wheatstone bridge and a voltage comparator. When pressure increases and the sensor resistance drops below R1, the comparator input U1 exceeds U1 and the comparator output goes high. The high output can trigger downstream devices for example, a relay to control LEDs, buzzers, motors, etc..
