New Product Post

In recognition of the holiday season and the sales that go hand-in-hand with it, Seeed is having a massive Thanksgiving sale.  We’ve really slashed the prices, and there are some hot deals.  After checking out the sale, don’t forget to take a look at our new products for this week.

We have a couple of solenoid valves that are perfect for low viscosity fluid control.  Keep in mind that a fluid is a liquid or a gas, so these valves are capable of controlling not only low viscosity liquids but gasses as well.  The G3/4 Electric Solenoid Valve (Normally Open) is perfect for applications that require continuous flow and only need to be shut it off for brief periods of time, like an emergency shut-off valve.  They generally require less power to operate and experience less wear-and-tear.Or we have the G3/4 Electric Solenoid Valve (Normally Closed) which only allows movement when the solenoid receives current.  This is commonly used in sprinkler systems, motion controlled faucets, dishwashers, etc.

If you’re looking to get into monitoring water usage, water management, or measuring if your water tank is full, we also have three different water sensors:  the G1/2 Water Flow Sensor, the G3/4 Water Flow Sensor, and the G1 ¼ Water Flow Sensor.  Choose your sensor based on the size of the pipe you are using and then connect the flow sensor to your Arduino or Seeeduino.  When the water flows through, the sensor will send a pulse signal to your board.  If you are eager to get started, one of our forum users has already contributed an example of how to read the water flow rate with the sensor.  It is located on the wiki page of all of our sensors.

Just in time for the holidays, we have the Renbotics Servo Shield v2.0.  This shield is a beast.  It has a PCA9685 which is an I²C bus controlled 16-channel LED controller.  It connects to your Arduino via I²C, and can handle up to sixteen servos per shield simultaneously.  In addition, the address of the board is selectable via a DIP switch.  As a result,it allows up to 62 devices on the same bus.So in theory you can connect up to 62 shields to your Arduino and run 992 servos at the same time.  It would be fantastic for a large animatronics holiday display, a robotics project, or mechatronic art.If servos aren’t your thing, then keep in mind that the 16 channels are all Pulse Width Modulation (PWM) outputs which work well with large LED projects, like displays and backlights.

Until next time, keep on making.
