R60ABD1 radar module is the use of 60G millimeter wave radar technology, detection of human skin subtle changes, through the algorithm to calculate the respiratory frequency, heartbeat frequency, motion amplitude, abnormal activity information.
Secondary development information: 1) Radar built-in algorithm processor, direct output results, no need for cloud computing 2) The detection results of radar are output by SCM serial protocol 3) Communication module (WiFi, 4G, etc.) is not included in the design of radar module.
Detection range: 1) Trigger range and accurate detection range of yunfan radar calibration 2) The maximum accurate detection range is usually within 40 degrees conical Angle within the design range of radar antenna.
3) The radar detection range can be adjusted by adjusting the Angle and distance 4) The detection accuracy is closely related to the detection target distance.
Usage: 1) Installed in a fixed position, accurate detection of external moving objects 2) Radar penetrates low density objects such as thin wooden planks. Caution False positives are caused by large detection range 3) Due to different electromagnetic wave noise in different environments, electromagnetic environment at the bottom of radar is required in some cases.

Whenever you and your family go for vacations, you may used to get worried about your plants because they need water on regular basis. We develop this Automatic Plant Watering System to solve this problem as plants need water according to the moisture level of soil..
The kit includes a plus controller, DHT22 temperature and humidity sensor, I2C LCD, push button modules, power amplifier module, DS3231 clock module, non-contact level liquid sensor, motor driver module, capacitive soil humidity sensor, and pump..
More than 13 well-selected electronic modules and 17 step by step creative tutorials. Full example code is provided and explained and even includes useful software tool..
Multi-purpose: timing watering mode, and the sensor detection mode that when the soil is dry, Arduino will command the water pump to run(up to 4 plants at once)..
Our system measures the soil moisture and waters automatically according to it. A audio power amplifier module tells us when the bucket is empty. I2C LCD displays the temperature and humidity..
