Abstract: Thyroid gland's ability to perform its functions is impacted by thyroid illness. Thyroid disease often comes in one of two forms: i) Hypothyroidism, which is characterised by (low function) and is brought on by insufficient thyroid hormones. ii) Overproduction of thyroid hormones, which results in hyperthyroidism (high function). Hypothyroidism can causeconstipation, dry skin, slow heartbeat, low energy, weight gain, inability to withstand the cold, and weariness. The signs of hyperthyroidism include irritability, weight loss, a rapid heartbeat, heat sensitivity, diarrhoea, and thyroid enlargement. A portion of the neck may bulge, a condition known as a goiter , in both hypothyroidism and hyperthyroidism.
The objective of this work is to create a low-cost smart sensing device that can measure the relative skin temperature, heart rate, and pulse of a human using a non-invasive technique for thyroid detection. It makes use of two separate sensors, one of which measures the patient's heartbeat, pulse rate and the other of which measures the relative difference in skin temperature. The variance detected by the sensors will be processed by the microcontroller. In this work, a heartbeat and pulse rate monitor built on an Arduino ide is used to count heartbeats per minute. Here, a Max30100 sensor is being operated, and when a finger is placed on it, it detects the heartbeat and pulse. This thyroid-detection method uses no pain or force.

Keywords: Relative skin temperature variation, Heartbeat monitor, pulse
