Flame Sensor Module
A flame sensor module is an electronic device used to detect the presence of flames or fire. It is commonly used in various applications such as fire detection systems, safety equipment, and industrial processes. The module typically consists of a sensor and supporting circuitry that helps in flame detection.
The flame sensor module works based on the principle of infrared (IR) detection. It uses an IR receiver to detect the infrared radiation emitted by flames. When a flame is present, it emits IR radiation that falls within a specific wavelength range. The sensor module is designed to detect this specific range of IR radiation and trigger a response.SKU: n/a -

Current Sensor ACS712-20A
The ACS712-20A is another variant of the ACS712 current sensor series. Similar to the ACS712-5A, the ACS712-20A is an integrated circuit (IC) module designed for measuring current in electronic circuits using the Hall effect principle. However, the ACS712-20A has a higher nominal current rating of 20A, making it suitable for measuring higher current levels.
This module provides an analog voltage output that is proportional to the current passing through it. The output voltage has a sensitivity of 100mV per ampere of current, meaning that for every ampere of current flowing through the module, the output voltage will increase by 100mV.
