Abstract
In this COVID-19 pandemic, a non-contact handheld infrared thermometer is frequently used for fever screening. However, the handheld thermometer performance depends on the operator and the distance to the forehead. To address these problems, we present an infrared thermometer on the wall (iThermowall). The iThermowall is a low-cost non-contact thermometer, adapted for the use of fever screening in public areas without an operator. The hardware can measure human body temperature automatically when the distance between the sensor and forehead is adequate. Temperature measurement validation of the iThermowall was conducted by T-test analysis. The results show that the P-values for all the test is more significant than 0.05, means that the mean Celsius temperature for both groups (reference thermometer and iThermowall) are similar. This article provides the 3-D printable open-source and the full source code firmware for the developing and under-resourced communities.

Summary
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been spread widely around the world through the airborne mechanism. SARS-CoV-2 can be stable in infected patients for up to 4 days [5] This viral stability at temperatures around normal body temperature implies that temperature may play a significant role in the transmission and severity of COVID-19. The guidance represented by Food and Drug Administration helps address these earnest public health worries by assisting with extending the accessibility of clinical electronic thermometers during this crisis, thereby helping to prevent potential shortages as the demand increases due to usage at critical locations [10]. In this COVID-19 pandemic, a non-contact handheld infrared thermometer is frequently used for fever screening. The hardware can measure body temperature automatically when the distance between the sensor and forehead is adequate
