Welcome to STL Controls Website

STL Controls has designed and built many controlled systems for factories,
petrol-chemical, marine industries. Examples of the systems that we had
built are as follows;

1. Valve Control System (Marine)
2. Star-Delta Motor Starting System (Manufacturing)
3. pH and Conductivity Monitoring System (Chemical Plant)
4. Lube Oil Heating System (Petrol Chemical Plant)
5. Water & Fuel Oil Tank Gauging System (Marine)
6. Automatic Water Pump Control System (Factory)
7. Air Bubbling System (Factory)





                pH & Conductivity Monitoring System
                  



We also provide customized electronics micro-controller packages to handle
the raw signal coming from industrial sensors such as pressure transmitter,
thermocouple, flowmeter, speed sensor, air pressure sensor, hall switches, etc..

Types of Micro-Controller:
1. Arduino Nano
2. ESP-01 (WIFI)
3. ESP-8266 (WIFI)
4. ESP-32 (WIFI)

Training on Programming of Arduino Micro-controller includes:
1. Digital Input / Digital Output
2. Analog Input (4 - 20mA sensor)
3. Analog Output (PWM - speed control of DC motor)
4. Switching ON AC/DC load with 5Vdc Digital Output (Relay or SSR)
5. Display data on I2C LCD and OLED
6. Using DTS1307 or DS3231 Real Time Clock (RTC)
7. Using Ultra-sonic Ranger Finder Module
8. Using HC-06 bluetooth unit with Android APPS
9. Using the Interrupt Service Routine (ISR) function
10. Obtaining raw data from environmental sensor with SDI-12 output
