On research wirelees sensor system design for monitoring velocity and direction of water. Monitoring the flow of water is needed in the field of irrigation and industry, mitigation of floods and many other applications. The system is made comprises a remote terminal unit (RTU) and control terminal unit (CTU). On the RTU are ATSAM3X8E microcontroller and microprocessor that transmit data through WiFi and received by personal computers that are in the CTU. RTU transmit the bases data to the CTU. The water velocity outtakes using waterflow sensor, which changes the magnitude of the flow rate to a variable frequency. Sensor waterflow associated with Schmitt trigger so that the output signal of the sensor is more accurate when read by the microcontroller. The frequency is read by the microcontroller and sent to a RTU computer. Flow direction in the sensor using a potensio that changed the angle (direction) into the barriers and voltage.

Abstract

A web based system design for soil moisture monitoring and automation was conducted on this research. Soil moisture level controlling is highly needed to optimalize plant cultivation result. The system contains of two main parts, a remote terminal unit (RTU) and control terminal unit (CTU).  RTU has an ATSAM3X8E microcontroller and a microprocessor used for acquiring and sending soil moisture level to database using internet connection. Using internet as telemetry connection is really efficient and gives many advantages such as measurement could be done in distance and also has realtime result. YL-69 sensor used for soil moisture level measurement gives resistance as the output value. This sensor has a module with a 10K ohm voltage devider resistor. The output sensor value converted into digital value using microcontroler analog to digital converter (ADC). This result then being compared with setpoint value to decide whether the water pump turning on or off. The output sensor value also sent and then saved in online database system through internet connection. A reference was used for determining sensor characterization with the linier formulation y = -0.0245x + 99.9560.  The result between sent and received data has no error, so there were no lost or gain data. The response from the sensor tested at setpoint value in 30, 40 and 50 giving errors 3.3%, 6.5% and 10.7% for each value. The system reponse tests showed that in a low setpoint value the system gave a very close value with the setpoint, but as the increasement of the setpoint value, the system got error increasement either.
