Hello everyone,
I need to track finger movements specifically how a hand closes and opens. I tried using MPU9250s but the problem is that only two sensors are supported by an ESP32 and I need to track the movement of each finger. I've tried multiple DIY flex sensors which were inaccurate and I can't use real flex sensors because this project has a budget cap of $40 (this is for school hence the budget cap). My project is to make smart rehabilitation gloves for people with arthritis which has a sensor that detects the person's movement and once the movement is detected servo motors assist the person. What sensors can I use for this project?
