Fully Automatic Manhole Monitoring Device using IoT

We build an IoT based Manhole Monitoring device. This device includes a gas sensor to monitor the gas presence in Manhole so that toxicity can be monitored, an ultrasonic sensor to detect the water level, and a tilt sensor to indicate whether the manhole cover is tilted. If any of these values go beyond the predefined values then we send an SMS to an authority number using the SIM800l GSM Module. This complete setup will be powered using a 18650 cell.
