Portable embedded system for the measurement of a vertical high jump

In this article we launch a low cost design of an embedded portable system to measure the height of a vertical jump through contact platforms. The “SALTOMETRO” , name given to the embedded system, can measure up to 32s of flight time with a resolution of 500μs, can calculate the vertical jump height and show it in a liquid crystal display (LCD) in less than 2s. “SALTOMETRO” consists of a microcontroller that operates in a 1MHz frequency, a LCD, a Li-Ion battery, a conditioning signal stage for passive or active circuits whit normally open (NO) or normally closed (NC) switches or signals and can use any type of contact platform, either commercial or made in laboratory does not require of a computer for its operation and the lithium ion battery (Li-Ion)of 1200 mA/h can last up to one week without recharge with an approximate use of 3 hours per day. The cost of construction is below $35 dollars.
