==User interface==
 
  
−
The user interface is written using PyQt5 - python binding for Qt v5.
 
−
 
−
The interface is divided into three sections.
 
−
* Setup control - Displays current value of slow control parameter and their evolution since the start of measurement. Also provides an interface to control the motor in the allowed range.
 
−
 
−
* Measurement - New measurements can be scheduled and started using this page. The details of the measurement completed are also shown in the bottom half of the page.
 
−
 
−
*Results - Completed measurements from the current run can be accessed with a simple plot showing the count rate of photons measured by the SiPM. It is also possible to add existing measurements by providing the directory where the measurements are saved.

==Motor control==
 
−
 
−
The stepper motor is controlled using Arduino.
 
−
 
−
==Pressure control==
 
−
 
−
The pressure is measured using MPT 200 and can be read visually from the inbuilt display. But, the pressure can also be read via serial connection.

==Tempretaure==
 
−
 
−
The temperature of the sample will be measured using a PT 100 sensor. The resistance of PT100 is 100 Ω at 0°C and increases linearly with temperature (138.5 Ω at 100°C). Using another resistor (1 kΩ) in the circuit, the change in resistance of PT 100 can be estimated as shown in [https://wiki.nikhef.nl/vuv/Sensor_connections#Temperature_sensor] .
 
−
 
−
The input voltage read using this circuit can be converted to temperature:
 
−
 
−
''resistance = (voltage)*1000 / (3.3-voltage)''
 
−
 
−
''temperature  = (resistance - 100) / 0.385''
 
−
 
−
==SiPM==
