  • Ultra-Thin & Responsive: The RP-C Pressure Sensor is a cutting-edge force sensitive resistor that offers rapid response times under 10ms. With a slim profile of just 0.4mm, this thin film pressure sensor is perfect for Arduino projects and other applications requiring precise pressure measurements within a 20g to 2kg range.
  • High Durability & Sensitivity: Engineered for over a million uses, the RP-C force sensor ensures consistent performance with less than 3% variance in resistance. Its high sensitivity triggers at a mere 20g of force, making it an ideal pressure sensor for Arduino enthusiasts and professionals alike.
  • Flexible & Versatile: This force sensor’s flexible design and static or dynamic pressure modes make it versatile for a wide range of applications. Whether for industrial use or DIY projects, the RP-C adapts to both static and dynamic pressures up to 10Hz frequency.
  • Stable & Reliable: With a default resistance threshold of less than 200kΩ for activation, the RP-C pressure sensor provides a stable and reliable performance. It operates flawlessly within a temperature range of -40°C to +85°C, ensuring durability and precision in various environments.
  • EMI & EDS Resistant: The RP-C pressure sensor is designed to be immune to electromagnetic interference (EMI) and electrostatic discharge (EDS), ensuring accurate readings without disruptions. Its hysteresis is maintained within +10%, demonstrating minimal deviation after a 24-hour static load of 1Kg.

I was working on a project to monitor the amount of liquid left in a glass or jar. I thought that using a force sensitive resistor like these from MakerHawk would be a good way to go. They look easy to use and control and the 2kg weight range is ideal for my purposes. After a few experiments I quickly realized that these devices weren’t very precise. They work by being sandwiched between two flat plates with a weight or other force applied across them. The electrical resistance decreases as the weight increases. The Amazon listing shows some very compelling plots demonstrating this working. In practice, I found that even a slight change in the angle between the two plates (e.g. if the load was moved a bit off-center) or if the plates weren’t perfectly flat, made a big difference in the measurement. I had to disband this idea completely and start looking at more complicated load-cells to weigh the glass.I think these FSR devices have utility – perhaps to detect whether a glass is present or not, but to make meaningful weight measurements looked to be a challenge.

As a DIY enthusiast dabbling in Arduino-based projects, I was on the hunt for a reliable and sensitive pressure sensor for another home automation project. The RP-C Thin Film Pressure Sensor caught my eye with its high sensitivity and ultra-thin design, perfect for integrating into compact designs and shrinkifying my projects! The responsiveness is crazy quick!!The durability claim is very interesting, they claim that it's engineered to withstand over a million uses with less than 3% variance in resistance; only time will tell if this holds up. It's sooooo thin that I am interested to see how that plays out! It also is rated to handle some pretty extreme temperatures from -40°C to +85°C, so I am going to use it in a trigger device in some outdoor applications in Texas over the summer! If it can handle that, then it is safe to say it can handle almost anything! LOL! All-in-all, these are super thin and make some pretty bold claims! Great value and I'll update my review if anything changes.
