Internal 1000 Ohm half-bridge strain gauge load cell, range is 50kg, half-bridge structure.
When measuring, the correct force is applied to the outer side of the strain E-shaped beam portion of the sensor (i.e., a strain gauge affixed to the middle, with a beam of white plastic cover arm) and the outside edges to form a shear force in the opposite direction, i.e., in the middle of strain beam bending necessary changes can occur under stress, strain beam side by another force can not have a barrier.
The sensor use the following three methods:
1, using a sensor with external resistors full bridge measurement range of a sensor range: 50kg. Higher requirements for external resistor
2, the use of only two full-bridge sensors measuring range is the range of the two sensors and: 50kgx2 = 100kg
3, the use of four full-bridge sensors measuring range is the range of four sensors and: 50kgx4 = 200kg

Reprap Stepper Driver A4988 Stepper Motor Driver Module Dropshipping color:Red
 
Description:
A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
   In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.

2) P1.2: signal being triggered again, start time again
3) P1.3: signal being triggered again, reset; disconnect relay, stop timing
P2: giving the trigger signal, the time after shutdown relay CL power relay OP time; then timing, turn off the relay
P3.1: give the trigger signal after the power relay on time OP, CL shutdown time relay; then operating cycle above cycle gaive signal again, shutdown relay stop timing; cycle times (LOP) can be set
P3.2: after connecting. no need to trigger signal, power relay on time OP, CL shutdown time relay; then the operating cycle above timea cycle (LOP) can be set
Q4: keeping the function of the signal; if there is no trigger signal, the time will be canceled, relay stay connected; when the signal disappears, timing OP turn off the relay; over time, if no signal again, the time is cleared
Time interval:
0.1 s (minimum) ~ 999 min (maximum) continuously adjustable
how to choose the time interval:
in the selection of parameter set interface mode, and press the STOP button to select the time
xxx. if the decimal point is in some place, the time interval is s-1 999 s
xx. x is decimal place is ten, the time interval is 0.1 s 99.9 s-
x. x. x is the decimal point are all on, the time interval is 1 min-999 min
parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, "---" is unlimited cycle)
How to set the parameter:
1. First make sure relay operation mode
2. According to the operaiting relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come intot main interface); long press SET key two seconds and then looen enter selection interface mode; by pressing UP, DOWN key to choose the mode setting
(P1.1 ~ P4)
3. After selecting the mode, press short SET to set the corresponding parameter, then the parameter you want to set will flash
(OP power in time; CL power off time; LOP cycle times, "---" is unlimited cycle ); by UP, DOWN to set the parameter value, support long press

Four Channel 4 Route MOSFET Button IRF540 V4.0 MOSFET Switch Module For Uno
Description:
MOSFET is an electronic devices with good switching characteristics. It is widely used in circuits, such as power supplies switching ,motor drives, lighting dimmer and so on. Relay is another kind of module with switching characteristics. Since relay works relying on mechanical contacts to open or shut. In this way it s will inevitably lead to relay's stopping working while switching time is too short. And papa sound made by relay in some situations is annoying.
We designed a 4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control.
In some extreme cases,It can be used to control 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is more than 9V.

4,HB100 is the use of microwave Doppler radar module (Doppler Radar) design principles of the microwave detector moving objects, mainly used in automatic door control switches, security systems, ATM ATM automated video control systems, automatic train signal, etc. place. HB100 is the standard 10.525GHz microwave Doppler radar detector, the detection method compared with other detection methods have the following advantages: 1, non-contact detection; 2, independent of temperature, humidity, noise, air, dust, light other effects, suitable for harsh environments; 3, anti-RF interference ability; 4, the output power is small, constitute a hazard to humans; 5, distance: more than 20 meters detection range.
5,Doppler Principle: Doppler theory based on time, when radio waves encounter an object in the moving process will be reflected when the waves, the frequency of the reflected wave will hit the object with the movement to change state. If the radio waves encounter an object position is fixed, then the reflected wave frequency and transmitting frequency waves should be equal. If the object moves toward the launch, then the reflected waves will be compressed, that will increase the frequency of the reflected wave; otherwise the reflected wave\'s frequency decreases.

CH340 USB To ESP8266 ESP-01 Wifi Module Adapter Computer Phone Wireless Communication Microcontroller Includes ESP-01 Wireless Module
 
 
Description:
100% brand new and high quality.
This moduel is an USB adpater / programmer for ESP8266 moduels of type ESP-01. 
It is conveniently fitted with a 2x4P 2.54mm female header to plug the ESP01 and configure or run it right away. 
A large 1000μF cap will help getting a steady 5.0V VCC from the USb bus and and jumper (on the right of the 2x4P header) will help configuring the GPIO0 line according needs. 
The module is based on the USB-UART bridget CH340 from WCH which is compatible with all platforms.
Note: For an usage with Arduino ESP8266 platform and Arduino IDE, it is necessary to switch manually the GPIO0 state for working mode, in order to get a fully automatic upload it is most likely possible, for a very limited effort, to assign an unused control line from CH340 to driver the GPIO0 line (probably at the cost of a necessary logic inversion).
