Microwave Doppler HB100 Radar Wireless Motion Sensor
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

Peltier Module Thermoelectric Cooler
Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side is used. You can also use temperature differential to generate electricity.
A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on.
When exposed to different temperatures on both sides it will also work as a generator and generate electricity depending on the temperature difference.

Si7021 Humidity Sensor Industrial High Precision Module
The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hysteresis, and excellent long term stability.
The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.
The Si7021 is available in a 3×3 mm DFN package and is reflow solderable. It can be used as a hardware- and software-compatible drop-in upgrade for existing RH/temperature sensors in 3×3 mm DFN-6 packages, featuring precision sensing over a wider range and lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulates. The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.

Soil Moisture Sensor Module For Arduino & Other
This is an easy to use digital soil moisture sensor. Just insert the sensor in the soil and it can measure moisture or water level content in it. It gives a digital output of 5V when the moisture level is high and 0V when the moisture level is low in the soil. The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output. When the moisture in the soil is less thatn the set threshold, the output remains low. The digital output can be connected to a microcontroller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a microcontroller to get the exact moisture level in the soil. This sensor is great for making water gardening projects, water sensing, etc.
