Measure Flight Time of Vertical Jump

Hello! I can assist you in making of flight time of a vertical jump. But first I would like to know more about it. I suggest you to use a switch on feet. I will discuss it in chat with you. This solution will be much economic for you. Arduino will detect the switch push condition on initial. When the person will take jump, the arduino will start to calculate till the switch is again pressed. This will be much faster and reliable system. To make it for high frequency please use INDUCTIVE PROXIMITY SENSOR - MAGNETIC SWITCH. It is much faster and will give you very high rate of sampling. Bid quote depends on project work, we will share.

Hola, soy desarrollador de prototipos electronicos, te hablo en español por que veo que eres de españa tambien no? Si podemos hablar de los detalles? para medir el salto vertical al 100% hay varias tecnicas. Una que si midiendo el tiempo de vuelo, otra que hacen en las oposiciones es marcando con una mano la altura y luego saltnado y restando la diferencia (se podria hacer un panel tactil donde guardara esos resultados o algo parecido. El tema de infrarrojo da un margen de tolerancia poco eficiente para esto Tambien se podria hacer con vision artifical con OpenCV si podemos hablar. Tambien he visto su propuesta muy baja, creo que lo primero para tener algo serio seria que se replantee el precio de la propuesta antes de empezar un saludo.

Hello sir, I have built this project before. At the beginning of the jump, the pressure under your feet is approximately zero and this changes when you land. I can provide schematic diagram and code for a working solution, then you can compare it with the code you already have. I look forward to working with you.

Hello, I cannot understand why a usual accelerometer (such as MPU6050) is not suited for your application. In fact it is an overkill. I guess you have problems with your free fall detection algorithm. Where is this sensor placed (on the hips...). I could assist you to debug your code. Otherwise you could use a contact matress. Please give more details...
