FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Features: LC 5A Over-current protection Sensor module uses current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A. Relay pull while over-current, relay released while not over-current. Users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection. Functions: -Current detection resolution can change the parameter of resistance parameters; -Output over-current switching signal output; -Over-current signal setting critical point adjustable, Specifications: Operating voltage: DC12V Operating current: Operating frequency range: 20Hz ~ 400Hz Output mode: switch signal output Maximum detection wire diameter: 5.2mm Mounting hole: hole diameter is 3mm, hole distance is 52.5mm Operating environment: -40 ￢ﾄﾃ ~ +85 ￢ﾄﾃ The current detection range:AC0.3A-5A Board size: 38 * 44mm The Board Description: VCC: Operating voltage positive; GND:Operating voltage negative; NO: Normally open, the relay pulls before the NO and COM disconnect, short-circuit after the suction; COM: common, relay common interface; NC: Normally closed, the relay before the NC and COM short-circuit, pull off after. Using Instructions: By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. As bellows: 1. Measured the wire through the current transformer, connect VCC and GND to DC12V power supply; 2. Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on, if connected to the relay means activated), then reduce or cut off the current flowing that through the tested wire, if the relay release at this time that over-current protection point has been identified (available to multimeter COM and NC measurement whether is connected, if connected to the relay means been released); 3. When reduce or cut off the current flowing through the wire, the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point.

Features: - Sensitive material MQ-9 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). - Detection method using low temperature cycling (1.5V heating) to detect carbon monoxide, conductivity sensors with carbon monoxide in the air increased with increasing gas concentration, spurious adsorption at high temperatures (5.0V heating) detection of combustible gases methane, propane and cryogenic cleaning gases. - Simple circuit can be used to change the conductivity, concentration of the gas is converted to the corresponding output signal. - MQ-9 high gas sensor for carbon monoxide, methane, liquefied petroleum gas sensitivity, the sensor can detect a variety of gases containing carbon monoxide and flammable, is a low-cost sensors for a variety of applications. Speciffications: 1. It adopts high quality double panel design with power indication and TTL signal output indication; 2. It has DO switch signal (TTL) output and AO analog signal output; 3. The TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the MCU or relay module) 4. The voltage of the analog output, the higher the concentration, the higher the voltage. 5. It has good sensitivity to gas and natural gas detection. 6, there are four screw holes for easy positioning; 7, product dimensions: 32 (L) * 20 (W) * 22 (H) 8, has a long life and reliable stability 9, fast response recovery characteristics Electrical Performance: Dection of gas: Carbon monoxide flammable gas Dection of Concentration:10-1000ppm(CO);100-10000(Gas) ppm Input voltage: DC5V Power consumption (current): 150mA DO output: TTL digital quantities 0 and 1 (0.1 and 5V) AO output: 0.1-0.3V (relatively non-polluting), the highest concentration voltage is about 4V Using the chip: AT89S52 Crystal: 11.0592MHZ Baud rate: 9600 Compilation environment: Keil Special Reminder: After the sensor is energized, it needs to be preheated for about 20S, and the measured data is stable. The heating of the sensor is a normal phenomenon, because there is a heating wire inside, if it is hot, it is not normal. Package Included: 3 x MQ-9 Gas Sensor Module
