GY-BMP280-3.3 High Precision Atmospheric Pressure Sensor Module for Arduino

 Description :                                                                    
Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!
This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter accuracy.

PIR - HC - SR505
HC-SR505 Mini Mini Body Sensor Module
            
Product parameters:
HC-SR505 small human body induction module is an automatic control product based on infrared technology. It has high sensitivity, strong reliability, small size and low voltage working mode. Widely used in various types of automatic induction electrical equipment, especially automatic control products powered by dry batteries.
Features:
Fully automatic induction: When a person enters its sensing range, it outputs a high level, and when a person leaves the sensing range, it automatically switches off the high level and outputs a low level.
Small size.
Repeatable trigger mode: After the induction output is high, if the human body moves in its induction range during the delay time period, its output will remain high until the person leaves. Low level (the sensor module will automatically extend a delay time period after detecting each activity of the human body, and use the time of the last activity as the starting point of the delay time).
Wide working voltage range: The default working voltage is DC4.5V-5V.
Micro power consumption: quiescent current <50 microamperes, especially suitable for automatic control products powered by dry batteries.
Output high level signal: It can be easily connected with various circuits.
Application:
Human induction lamps    
Human induction toys
security product         
Industrial automation control
Automatic induction electrical equipment 
Battery-powered automatic control, etc.

DHT11 Humidity & Temperature Sensor compatible with arduino

Description

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

LM35DZ Temperature Sensor for Arduino

The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low-output impedance, linear output, and precise inherent calibration of the LM35 device makes interfacing to readout or control circuitry especially easy. The device is used with single power supplies, or with plus and minus supplies. As the LM35 device draws only 60 µA from the supply, it has very low self-heating of less than 0.1°C in still air. The LM35 device is rated to operate over a −55°C to 150°C temperature range, while the LM35C device is rated for a −40°C to 110°C range (−10° with improved accuracy). The LM35-series devices are available packaged in hermetic TO transistor packages, while the LM35C, LM35CA, and LM35D devices are available in the plastic TO-92 transistor package. The LM35D device is available in an 8-lead surface-mount small-outline package and a plastic TO-220 package.
