5Pcs 5V 1-Channel H/L Trigger Optocoupler Relay Module For Arduino Description: The module uses genuine quality relay, normally open interfaces Using SMD optocoupler isolation, driving ability, stable performance The module can be high or low by a jumper setting trigger Fault-tolerant design, even if the control line is broken, the relay will not operate The power indicator (green), the relay status indicator (red) The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient Specification: Maximum load: AC 250V/10A, DC 30V/10A Trigger current: 5mA Working voltage: 5V Module size: 50 x 26 x 18.5mm (L x W x H) Four mounting bolts holes, diameter 3.1mm Module interface: DC+: positive power supply (VCC) DC-: negative power supply (GND) IN: can be high or low level control relay Relay outputs: NO: normally open relay interface COM: Common Interface Relays NC: normally closed relay interface High and low level trigger options: It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin Package included: 5 x 1 Channel H/L trigger optocoupler relay module

5Pcs Infrared Obstacle Avoidance Sensor For Arduino Smart Car Robot Description: The sensor module light is adaptable to the environment, the working voltage of 3.3 V to 5 V. It has a pair of infrared transmitting and receiving tube, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube. After the comparator circuit processing, green indicator will light up, at the same time the signal output interface output a digital signal (a low level signal), can be adjust the detection distance through the potentiometer knob, effective distance range 2 ~ 80 cm, easy to assemble and use. So it can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and so on many occasions. Package included: 5 x Arduino obstacle avoidance sensor

5Pcs HC-12 433 SI4463 Wireless Serial Module Remote 1000M With Antenna Note: HC-11 cannot communicate with the HC-12, they work independently, in pairs Features: Supply voltage: 3.2V~5.5V. (If the module you want to work long hours in the emission state, it is recommended that when the supply voltage exceeds 4.5V threaded a 1N4007 diode to prevent module built-in LDO heated) Default address range (open field test): About 600m (maximum communication distance adjustable reach 1000m, the baud rate is 5000bps) Default idle current: 16MA (In different working modes operating current is different) Module dimensions: 27.8 x 14.4 x 4mm Operating frequency range: 433.4-473.0MHz, up to 100 channels of communication The maximum transmit power: 100mW (settable) Module support software upgrade Default factory settings: Mode FU3, baud rate is 9600bps, communication channels CH001 (433.4M) Package included: 5 x HC-12 433 Serial module AT command set:   Module parameters, AT command set AT command is used to set the parameters of the function module and switching modules need to exit the setting mode after setting to take effect. Meanwhile, modify the parameters and functions, power-down is not lost.   Enter the command mode: The first entry mode - normal use (has the power) in the first 5-pin "SET" is set low; The second mode of entry - power, 5th pin "SET" again first set low on power. Both methods can make the module into AT command mode, release ("SET" pin is not connected low) to exit command mode. After the exit command mode, if you change the module function, the function will be cut to the appropriate state. The second way is fixed in serial format 9600, N, 1 into the AT.   Instructions: 1. AT Test instructions Example: Send module commands "AT", the module returns "OK".   2. AT + Bxxxx Change the serial port baud rate command. You can set the baud rate is 1200bps, 2400bps, 4800bps, 9600bps, 19200bps, 38400bps, 57600bps and 115200bps. The factory default is 9600bps. Example: Set the module serial port baud rate is 19200bps, please send module command "AT + B19200", the module returns "OK + B19200".   3. AT + Cxxx Change the wireless communication channel, selectable from 001 to 127 (more than 100 radio channels after the communication distance not guaranteed). The default value is 001 radio channels, operating frequency is 433.4MHz. Step channel is 400KHz, the operating frequency of the channel 100 is 473.0 MHz.   Example: Set module to channel 21, please send module command "AT + C021", the module returns "OK + C021". After exiting the command mode, the module in the first 21 channels, operating frequency is 441.4 MHz. Note: Because the wireless receiver module sensitivity HC-12 is relatively high, the baud rate is greater than when air 58000 bps, 5 must be shifted to the adjacent channel use. When the air baud rate is not greater than 58000 bps, if the short distance (10 meters) communication, but also need to stagger five adjacent channel use.   4. AT + FUx Change the module serial pass-through mode, there FU1, FU2 and FU3 three modes. Module default mode is FU3, two serial pass-through mode module must be set to the same communication. See detailed above, "wireless serial pass-through" part. Example: Send module commands "AT + FU1", the module returns "AT + OK".   5. AT + Px The default setting is 8, maximum transmit power, communication distances. Transmit power level is set to 1, the minimum transmission power. In general, the transmission power of each drop 6dB, communication distance will be reduced by half. Example: Send module commands "AT + P 5", the module returns "OK + P5". After exiting the command mode, the module transmit power is +11 dBm. Package included: 1 x HC-12 module
