KY 011 KY-011 Two Color Red and Green LED Common Cathode Sensor Module In Pakistan

ECG Electrodes with Metal Snap and Low Impedance Solid Medical Conductive Gel Disposable ECG electrodes are used for diagnostic ECG or ECG monitoring They can be used for various ECG tests Chunfeng and reg; Disposable ECG electrodes use an AG/AgClsensor element and solid conductive and adhesive Hydro-gel for adhesion The AG/AgCl sensor element has the best sensitivities and the solid conductive and adhesive hydro-gel has very low impedance and is non-irritating, non-sensitizing and non-cytotoxic to the skin All electrodes are latex-free.

The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40°C to +85°C extended temperature range. MAX9814 is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator, and AGC control circuitry. The low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB. A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attack/release times. A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones.

MQ2 MQ-2 MQ 2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, the measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by a potentiometer.MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the sensor’s conductivity with increasing concentration of combustible gas in the air increases. Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.MQ-2 gas sensor higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas, and other combustible vapors are ideal. This sensor can detect a variety of flammable gas, are a low-cost sensor for many applications.
