Smart irrigation systems tailor watering schedules and run times automatically to meet specific landscape needs. These controllers significantly improve outdoor water use efficiencies.
Unlike traditional irrigation controllers that operate on a preset programmed schedule and timers, smart irrigation controllers monitor weather, soil conditions, evaporation and plant water use to automatically adjust the watering schedule to actual conditions of the site.

Density Based Traffic Signal System:
At the present time, the traffic control system becomes the main issue because of the fast increase in automobiles and also due to large time delays between traffic lights. So, in order to overcome this problem, we will go for density based traffic light timing control system. This article discusses how to control the traffic based on density.The proposed system uses IR sensors to calculate the traffic density. We have to place one IR sensor on every road; where the sensor always senses the traffic on that specific road. All these sensors are interfaced to the microcontroller. Based on the sensors, microcontroller detects the traffic and controls the traffic system.
The aim of the traffic control system project is to solve traffic congestion, To solve the problem, we have designed a framework for a dynamic and automatic traffic light control system and developed a simulation model with codes to help to build the system on hardware.
It is possible to propose dynamic time-based coordination schemes where the green signal time of the traffic lights is assigned based on the present conditions of traffic. This is achieved by using 3 pairs of IR sensors (Transmitter and Receiver) across the road to monitor a particular length/zone while vehicles on the same zone block the IR light falling on the IR receiver to assume low traffic density.
As there are 3 zones only, it is immaterial if vehicles are parked side by side. As it crosses the zone, the green time automatically changes as programmed.
