LDTR-WG0237 Plant Watering Alarm Humidity Moisture Sensor for Arduino (Black)
- This is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. It uses capacitive humidity sensing as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil, avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.
- Special care has been taken not to make it yet another source of annoyance - This sensor will be silent when its dark and will restrict itself from making too much noise.
- The alarm level can be set for each plant individually. As water is consumed by the plant, it will detect the low moisture level and will start to emit rare short chirps. As more water evaporates, it will increase the alarm rate. This sensor can detect if its day or night by measuring the amount of ambient light and will not make noise when its dark.
- Package included: 1 x Plant Watering Alarm Sensor

LDTR-WG0238 X9C104 Digital Potentiometer Module For Arduino (Blue)
- In resistance tester circuit, it is necessary to adjust the potentiometer to balance the resistance tester. Under the influence of temperature, humidity and vibration impact, the position and specifications of the potentiometer will be changed when being used, the system index is also changed. Therefore, to make the system back to the original state it needs to be adjusted, and digital potentiometer module can just solve this problem.
- The digital potentiometer changes in steps or incrementally, and the resistance is of linear change. For example, the resistance range of X9C104 is 40R~1000k, divided into 100 steps, so each increment is 1010R.
- With temperature compensation function: the resistance deviation between endpoints is +/-20%;
- Sliding end data can be kept for a long time, about 100 years;
- With 1% high resistance resolution;
- Working voltage: 5V;
- Total resistance: 100k;
- End voltage: -5~5V;

Waveshare JetBot AI Kit, AI Robot Based on Jetson Nano
- Overview
- Smart robot is always the favorite project of electronic enthusiasts, however, a robot will be "not that smart" if it is not AI-based.
- Welcome the JetBot, an actual smart robot powered by Jetson Nano. With the intelligent eye (front camera), facial recognition, object tracking, auto line following, and collision avoidance can be easily achieved. It also comes with ROS nodes code, which makes it easy to get started with the open source ROS (Robot Operating System), and to learn the system framework and concepts of ROS.
- Adopts 3x 18650 batteries (NOT included), high battery capacity, up to 12.6V voltage output, more powerful driving force.
- Integrates S-8254AA + AO4407A lithium battery protection circuit, provides protections for over-charge, over-discharge, over-current, and short circuit.
- Onboard APW7313 voltage regulator, provides stable 5V voltage for the Jetson Nano.
- Onboard TB6612FNG dual H-bridge motor driver.
- Onboard 0.91inch 12832 pixels OLED, allows to display robot IP address, RAM, battery life, etc.
