This is a force sensitive resistor with a square, 1.75x1.5, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1 pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR. These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale. Dimensions: Overall length: 3.5 Overall width: 1.75 Sensing area: 1.75 x 1.5. | ![]() B085VYBJ3N Price: $16.1 Score: 6.289 Category: Electronics Rating: 2.6 Votes: 3 Find similar productsMultifunctional PWM Signal Voltage Current Converter Module PWM Signal to 0-20MA 0-3.3V/0-5V/0-10V Voltage to 0-20MA.

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9600 does all that for you, and can be easily interfaced with any microcontroller or single-board-computer with I2C. Inside, the chip handles all the analog stuff for you, and can interface with just about any thermocouple type: K, J, T, N, S, E, B and R type are all supported! You can also set various alerts for over/under temperature, and read the thermocouple (hot) temperature and the chip (cold) temperature. All this over common I2C This breakout board has the chip itself, a 3.3V regulator and level shifting circuitry, all assembled and tested. Works great with 3.3V or 5V logic. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). Match it up with our 1m K-type thermocouple. Works with any K, J, T, N, S, E, B and R type thermocouple Datasheet rated for: K Type: -200°C to +1372°C J Type: -150°C to +1200°C T Type: -200°C to +400°C N Type: -150°C to +1300°C E Type: -200°C to +1000°C S Type: +250°C to +1664°C B Type: +1000°C to +1800°C R Type: +250°C to +1664°C Resolution of ±0.0625 °C - note that K thermocouples have about ±2°C to ±6°C accuracy Internal temperature reading 3.3 to 5v power supply and logic level compliant I2C data connection. |
