Altitude measurement in fields, forestry and engineering remain essential but still conventional methods of altitude measurement remain challenging. Present altitude measurement methods include height poles for trees and photogrammetric instruments. Both methods remain arduous as either process is both time and money consuming or susceptible to large parallax errors. In this innovative work an altitude and distance calculating device out of potentiometers based on trigonometry was developed. A laser diode was attached to a potentiometer, and the other components were soldered together in a circuit board. Device accuracy and precision was determined. User satisfaction survey was also noted. For the altimeter testing, the lasers were pointed at the top of the object and the device was placed at a 1-meter distance from the base of the object. The device was set to measure different heights from 0.5 m to 2.5m. For the distance sensor, the lasers were pointed at a 1-meter height and the device was set to measure different distances from 0.5m to 2.5m. Three replicates for each trial were performed and device readings were then compared to actual measurements to determine accuracy. Standard deviations of reading were then computed to determine precision. Net Promoter Score was used in order to assess external evaluator feedback. An Arduino based altimeter and distance sensor was successfully fabricated with 94.2 percent degree of accuracy and 95.4 percent precision for height measurement. For the distance sensor, a 91.4% accuracy, and 95.4% precision was determined. The device garnered a net promoter score of 66%.
