This study aims to provide a solution to ease people in the retail industry to comply with the Standard Operating Procedure (SOP) by implementing Smart Counter and Temperature Detector (SCATD) in their premises. Two Infrared (IR) sensors are connected to Arduino UNO to detect people entering and exiting the premise. The counter counts the people in the premise based on the reading of the IR sensor. Digital noncontact Infrared temperature sensor (MLX90614) and APDS- 9960 digital RGB, ambient light, gesture and proximity sensor are also connected to Arduino UNO for the temperature detector. By using APDS-9960 sensor, temperature will be taken only if the object is in front of the sensor. The temperature detector will also function according to the IR sensor. If the IR sensor at the entrance door detects a person entering the premises, it is compulsory for that person to screen their body temperature. If not, the alarm will be activated to let the customer know that they have not screened their body temperature yet. This is to prevent people from entering the premises without screening their body temperature. The temperature data from Arduino UNO is transferred to the ESP8266 server through serial communication. Then, from the ESP8266 server, the temperature data is sent to the ESP8266 client that is located at the counter cashier so that the worker can monitor the temperature data of every customer coming into the premises. If the customer's body temperature exceeds 37.5 °C, the alarm is activated to notify the worker and prevent the customer from entering the premises. This system has demonstrated that it indeed can help ease the process of complying with the SOP.
