Grove - Speech Recognizer
Sold outThe Grove speech recognizer is a module designed for application in the smart home, toy, robot or anything you would like to control with voice commands.
Overview
The board includes a Nuvoton ISD9160, a microphone, 1 SPI flash, 1 grove connector, 1 speaker connector and 1 led to show to your voice activity.
Nuvoton ISD9160 is (SoC) Chipcorder that based on Cortex™-M0, it provides performance and the energy efficiency needed for voice control applications. The microphone on grove-speech recognizer is Omni-directional.
This speech recognizer can recognize 22 commands including ‘start’, ‘stop’ and ‘Play music’. Every time it recognizes a command, it will return a value and the connected loudspeaker will repeat the command. This value can be used to control other devices like a motor or music player.
Note: The wake up word is “Hicell” (Pronounce it as one word). When it recognizes the awaken word the LED turns red and you can say the command word. If it recognize the command word, the LED will turn blue.
Note: The firmware of the module was wrote by the third party vendor, it’s not open source.

Easily monitorize your garden's environment with simple components.
Greenhouses are excellent ways to grow plants due to their compact nature and the fact that they can absorb and store the sun’s light as heat to keep their internal temperature higher than outside. But when it comes to adding ventilation for cooling things down, decreasing the humidity, or simply to avoid rain, most non-commercial ones still rely on someone to manually open or close the windows. This need for automation is what drove Michael Bernhard to create his own greenhouse climate regulation system. This project relies on a Nano Every to read the ambient temperature/humidity as well as control up to six motorized windows via three L298N dual H-bridge drivers. The Nano receives commands and other data over WiFi from an accompanying ESP8266 board for wireless remote control with a mobile phone. Each of these components and their connectors were added to a custom PCB and placed within a simple wooden enclosure to keep moisture out. An LCD at the top shows pertinent information such as the time, temperature, and humidity. The aforementioned WiFi control scheme not only allows for remote control of the windows, but also for the visualization of historical sensors data on a graph. Safety information, including errors and stored EEPROM data, can be viewed on the web application, too. To see more about this project, you can read Bernhard's write-up here on Hackster.io.
