Teaching Standards:
Exhaled breath humidity measurement is proportional to the amount of water vapor that is being lost by a human body. In this module, a Raspberry Pi with the SenseHAT is programmed to measure relative humidity and indicate the level of humidity using the 8 x 8 LED matrix. Each LED when turned on will represent 0.64% relative humidity. The module can also be used as a game by comparing the amount of relative humidity a human can exhale within a fixed time interval. The instrument can also be used as humidity indicator and a device to control a humidifier.
