Radio Microwave Antenna NSMA Pattern

Radio Microwave Antenna NSMA Pattern

For Radio Microwave Path Calculation

This section would describe NSMA Pattern for Microwave antenna Path Calculation Software or Application like PathLoss, which able to summaries as table below.

After finish Microwave Antenna curve in our application would show as picture below

MCS-51 Temperature and computer control

Worthwhile micro-controller use AT89C2051 Hardware detail as below
1. Port P1.0-P1.4 connect to Relay drive ULN2003
2. P1.5-P1.7 check input signal 12VDC
3. Int0 connect to temperature sensor DS1820
4. Rx Tx connect RS232 circuit

Mention to Keil C programming code work properly detail as below

Worth-While Temperature controller concept

Temperature controller with variety application
example
- hatchery









As the picture show temperature control including
1. computer software make us able to do automatic temperature control or manual control, which software control make us minimize micro-controller hardware cost
2. Small Microcontroller with additional digital temperature sensor and water level checker assist accuracy temperature control

3. Small Application software operate in Windows ME and Linux, which make us use worth-while old computer
