i want to make a simple circuit diagram

The circuit consists of two HC-SR04 ultrasonic sensors, an Arduino Nano, four LEDs, and two active buzzers. The ultrasonic sensors detect vehicles approaching the blind curve and send distance information to the Arduino Nano. The Arduino processes these inputs and determines whether a vehicle is present on either side. The green LEDs indicate a clear road, while the red LEDs and buzzers provide warnings when a vehicle is detected. If vehicles are detected on both sides simultaneously, both red LEDs and buzzers are activated to indicate a possible collision risk. Input → Processing → Output: HC-SR04 sensors → Arduino Nano → LEDs + Buzzers.

Glycol cooling circuit for dairy process machine. 24vdc from machine control panel (L24.120), To PID controller, out the PID controller, then through a solid state relay (SSR-1), Then into float switch (when tank full, switch is closed), this then feeds back to PLC input (I0040 - Alarm cooling circuit). also, 24V (L24.120) supplies another output on the pid controller, that output then goes to a glycol solenoid valve. There is also a pump, which is run through a 3 pole contactor, from 230vac (from the control panel). the solid state relay (SSR-1) coil is energised by the 230v from the pump contactor. also the PID controller power supply is ran from PLC output Q0036 (24vdc).
