The new AirMouse Ambient Air Density sensor module measures the power potential of air entering all naturally aspirated, turbo, and supercharged engines. The mouse shaped sensor is a rugged military-grade weather station with scientific accuracy. The waterproof module utilizes a Gortex(R) vent to allow for precise measurement of pressure, temperature, and humidity while protecting the electronics inside. The compact sensor module mounts in the vehicle's grill or air intake to constantly monitor the characteristics of the available air, which directly impacts engine performance.
