This Project and presentation is created by 'Shanjedul Hassan' ABSTRACT Despite the perception people may have regarding the agricultural process, the reality is that today’s agriculture industry is data-cantered, precise, and smarter than ever. The rapid emergence of the Internet-of-Things (IoT) based technologies redesigned almost every industry including ‘‘smart agriculture’’ which moved the industry from statistical to quantitative approaches. Such revolutionary changes are shaking the existing agriculture methods and creating new opportunities along with a range of challenges. This article highlights the potential of wireless sensors and IoT in agriculture, as well as the challenges expected to be faced when integrating this technology with the traditional farming practices. IoT devices and communication techniques associated with wireless sensors encountered in agriculture applications are analyzed in detail. What sensors are available for specific agriculture application, like soil preparation, crop status, irrigation, insect, and pest detection are listed. How this technology helping the growers throughout the crop stages, from sowing until harvesting, packing, and transportation is explained. Furthermore, the use of unmanned aerial vehicles for crop surveillance and other favourable applications such as optimizing crop yield is considered in this article. State-of-the-art IoT-based architectures and platforms used in agriculture are also highlighted wherever suitable. Finally, based on this thorough review, we identify current and future trends of IoT in agriculture and highlight potential research challenges.

7. Moisture Sensor
This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the
plants in your garden reach out for human help. They can be very to use, just insert it into the soil and then read it.
If you are a gardener, you can use this sensor to know when your plants need to be watered.

12. DHT22 Digital Temperature Humidity Sensor
The DHT22 is a basic, 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).
◦ Power supply: 3- 5V.
◦ Current: 2.5mA max use of current during conversion (while requesting data).
◦ Humidity: 0 - 100%, ± 2%.
◦ Temperature: -40°C + 125°C, ± 0.5%.
◦ The sampling rate no more than 0.5 Hz (once every 2 seconds).
