Air and water pollution are the causes of global warming. The first step towards stopping pollution is to be able to measure it. People need to know the exact pollution level they are standing in so that they can respond to it. In this age of smart watches, we have watches to track our own health and fitness, but what about environmental health. If environmental health degrades so will the health of all humans and future generations too.
So here we develop a smart watch that also measures air and water pollution along with displaying time. With this people will no longer special equipment to measure pollution levels, they can monitor pollution levels anywhere and anytime desired. This battery powered smartwatch system is operated by an STM32 controller along with a air quality sensor, gas sensor, ph sensor, turbidity sensor and mini display. The smart watch is a combination of sensors and electronics to enable every citizen monitor and protect our environment.
The air quality sensor is used to detect the amount of air pollution in the air as ppm levels. This data is processed by microcontroller to get the current air quality. The watch also monitors for any flammable gases in the vicinity to detect any flammable gas leakages using flammable gas sensor. This sensor is constantly monitored by controller. Now we have a ph sensor that is used to detect the ph level of any water body. The user can just dip the ph sensor on his/her smart watch to get ph level. The sensor data is processed by controller and displayed on the display module.
Similarly we here have a turbidity sensor attached to the smart watch as well. The sensor is used to transmit the water turbidity value to controller which is displayed on display. Ph and turbidity are used to display water quality of any water body (lake, pond, canal, sea). The smartwatch allows to set high and low acceptance values of each parameter using push buttons. If any of the values scanned shows up higher/lower than set limits it sounds a buzzer alert as well displays the alert message on display to the user.
