{"title":"4x8 Flexible Tactile Pressure Sensor with UART","handle":"4x8-flexible-array-tactile-pressure-sensor-uart-cascade-support","url":"/products/4x8-flexible-array-tactile-pressure-sensor-uart-cascade-support","description":"This flexible tactile pressure sensor gives your project a compact 4 x 8 pressure matrix for mapping contact across a small surface. It integrates 32 independent sensing points in a 20 x 10mm active area, making it useful for robotic grippers, electronic skin, wearable electronics, human-machine interaction and research setups.The thin-film FPC sensor is designed for tight spaces and curved contact areas, with adhesive backing for easier mounting. A compact adapter board handles the sensing interface, so you can read matrix pressure data over UART instead of building separate analogue acquisition circuitry for each point.UART cascade support helps reduce wiring complexity in multi-sensor prototypes, and the module is suited to Arduino, ESP32 and Raspberry Pi ecosystems. The kit includes the adapter board, the 4×8 flexible array pressure sensor and a 30cm flexible silicone connection cable.Features:4 x 8 tactile matrix with 32 independent pressure sensing points20 x 10mm compact sensing area for high-density pressure mapping2.5mm sensing point pitch for localised force distribution detectionResponse time below 10μs for dynamic tactile signal captureUART communication interface with cascade supportCompatible with Arduino, ESP32, and Raspberry Pi ecosystemsUltra-thin flexible FPC structure for electronic skin-style integrationAdhesive backing for easy mounting on compact or curved surfacesDurability above 1,000,000 cycles at 1kg forceRepeatability of ±5% for long-term pressure sensing applicationsSpecifications:Operating Voltage: 5VSampling Frequency: 20Hz / 50HzSensing Area: 20 x 10mmArray Configuration: 4 x 8 (32 points)Communication Interface: UARTTrigger Force: 20gPressure Range: 20g ~ 5kg (per sensing point)Pressure Type: Compression/PressingDurability: >1,000,000 times (at 1kg force)Operating Temperature: -20℃ ~ +65℃Adapter Board Size: 20 x 12mmA strong fit for smart grippers, tactile feedback experiments, wearable pressure monitoring and compact interactive controls.","vendor":"DFRobot","product_type":"Pressure Sensor","in_stock":true,"options":[],"variants":[{"id":15904,"title":"Default Title","sku":"DF-SEN0705","mpn":"SEN0705","price":39.1,"on_sale":false,"in_stock":true,"available_quantity":41}]}
