A procedure in which two or more metal products are fixed as one by liquefying and running a space filler metal solder in the joint is known as Soldering. The space filler metal has lower liquefying or melting temperature than the work piece.
Join For Free Over the last two weeks in my free time I have been working on a system to automate a greenhouse or an open field. The system is designed using Arduino Nano and Raspberry Pi. The Arduino is used to read sensors and control devices, and the Raspberry Pi is the brain that decides what to do when an event is detected by the Arduino.
The systems communicate wirelessly via XBee. In a normal scenario on a farm we have to: Switch on the drip irrigation pump when the soil humidity is low. Switch on the main motor that connects to a water source when the reservoir level goes down.
Switch off the main motor when the reservoir is full. Below is a very ugly drawing I came up with to explain the system. The system is very generic and based on configurations, so nothing is hardcoded. The XBee connected to the Pi acts as the coordinator and receives periodic sensor inputs from Ardunio connected in the field.
This system can issue commands to control devices based on the sensor inputs. From the above picture you can see there are five Arduinos in the field sensing different parameters.
For now let's think that they all read the soil humidity. Say soil humidity values range from 0 towhere 0 is dry and is fully wet. We need to switch on the drip irrigation motor when any of the sensor values is less than Once all the sensors give a humidity value greater than 90 we need to switch off the motor.
As you can see the system needs to take action based on the values coming from the sensor. Depending upon the crops, these values can be changed. In the central system, we can group the sensor nodes and configure the triggering points.
We can also configure what to do when the triggering points are reached. For example, in the above case we can say when the soil humidity of any sensor goes below 20, then send the motor "switch on" command to the node sitting next to the reservoir motor.
To switch off the motor the system needs approval from all the sensors, which means the motor will get switched off if all the nodes reported value is greater than What happens when a sensor node dies without sending soil humidity a greater than 90 value?
Will the motor run whole day? The central system can be configured for that too, and during configuration we can set up a timeout period. If the central system is not receiving high water level signals after a configured time, it automatically sends a switch off command to the desired Arduino node to switch off the motor.
From the above diagram, we can see there are two reservoirs and one main motor. The main motor needs to switch on to fill the reservoir. Each reservoir is equipped with sensors to detect the high and low water levels.This paper designs a community automatic irrigation control system based on Zigbee aiming at the shortcomings of existing community plant irrigation and the characteristics of the community.
The green space of the community is divided into a plurality of irrigation area, each irrigation area and main control module adopts distributed structure network, using TIs CC as the core processor of.
