It’s easy to overheat. Whether you’re exercising, spending time outdoors, or even sitting in a poorly ventilated room, one can find their body temperatures rising to uncomfortably high levels. You might even experience heat stroke, dehydration, and other dangerous side effects from significant exposure to the heat.
The concept of this device is simple – using a DHT Sensor to read the temperature of the room, an alarm and LED will alert the owner that they should grab the sensor in order to activate the motor and fan. This creates more airflow that will keep the user cooler and more comfortable.
CIRCUIT SCHEMATIC
PROTOTYPE (Portable and Tabletop Versions)
CODE
The code begins by checking the temperature of air with the DHT 11 sensor. If the air is above 27 degrees celsius, the red LED and buzzer are triggered letting the user know that it is too hot in their area.
From there, the user will grab hold of the trigger, in this case the soil moisture sensor, and the slight change in moisture from the user’s hand will activate the motor fan, and the green LED, while deactivating the red LED and the buzzer.
When the trigger is released, and if the temperature now reads as below 27 degrees Celsius, the entire system will turn off until the temperature rises again.
