Abstract
A handheld moisture sensing device for use in determining the moisture content of biological material, such as animal feed. Adapted to be pressed against biological material to be analyzed, the device includes a sensor assembly, including a housing with an end structure including a grate adapted to engage the material to be examined, a near infrared (NIR) LED, an NIR light sensor, a glass mounted in the housing adjacent the light source so that light from the light source passes through the glass, a glass heater positioned adjacent the glass for heating the glass, a lens mounted in the housing adjacent the NIR sensor so that the NIR light reflected off the biological material passes through the glass and is focused by the lens onto the NIR sensor, and a controller connected to the NIR sensor and receiving a signal related to the reflected NIR light received by the NIR sensor.
