The Urban Garden Monitor, powered by a WIZnet WI Original author: Chen Jian (source: https://www.elecfans.com/soft/Mec/2022/202212131956672.html) ## Article ## escribe ![pYYBAGOSmhSATDLVAAcSkn_s2d8613.jpg](https://file.elecfans.com/web2/M00/82/24/pYYBAGOSmhSATDLVAAcSkn_s2d8613.jpg) Urban Garden Monitor is running. The device allows a fast, safe and remote analysis of the environment around urban gardens. The Urban Garden Monitor, powered by a [WIZnet](https://bbs.elecfans.com/group_696) WIZ750SR serial-to- [Ethernet](https://www.elecfans.com/tags/%E4%BB%A5%E5%A4%AA%E7%BD%91/) module and [Arduino](https://www.elecfans.com/v/tag/62/) 101, reads temperature, humidity and pressure data and classifies them into a category system using an integrated neural [network .](https://www.elecfans.com/v/tag/1722/) The device was created using some intertwined ideas: ### WIZnet WIZ750SR serial port to Ethernet module ![pYYBAGOSmkSAIn6LAAbhFpmJQLY212.jpg](https://file.elecfans.com/web2/M00/82/24/pYYBAGOSmkSAIn6LAAbhFpmJQLY212.jpg) WIZ750SR on Urban Garden Monitor. WIZ750SR is a serial-to-Ethernet module that allows any device with a serial port to connect to the Internet. The module uses the W7500P processor which combines an [ARM](https://www.elecfans.com/soft/data/21-25/) Cortex-M0 with 128KB flash memory and a hardwired TCP/IP core for seamless connection between serial data and Ethernet data. In Urban Garden Monitor, the WIZ750SR bridges the gap between the environmental data collected by the Arduino 101 and the TCP client terminal accessible on any device connected to the same router as the WIZ750SR. ### Arduino 101 and Pattern Matching Engine [Neural Networks](https://www.elecfans.com/tags/%E7%A5%9E%E7%BB%8F%E7%BD%91%E7%BB%9C/) The Arduino 101 is a unique development board that functions as an [Intel](https://www.elecfans.com/tags/%E8%8B%B1%E7%89%B9%E5%B0%94/) Curie module in an Arduino form factor. Features real-time operating system, integrated BLE, six-axis accelerometer/ [gyroscope](https://www.elecfans.com/tags/%E9%99%80%E8%9E%BA%E4%BB%AA/) module, and 128-node pattern matching engine (PME) or artificial neural network. Urban Garden Monitor leverages [RTOS](https://www.elecfans.com/tags/RTOS/) and PME to provide optimized characterization of daily environmental data into a 30-class library that fills up as the device learns different classifications of this data, allowing users to visualize data trends and adjust them as needed The Garden. The Arduino 101 also comes with an additional [hardware](https://www.elecfans.com/v/tag/1751/) serial port which is critical to the operation of the WIZ750SR and acts as a link between the two devices. ### BMP180 and DHT22 Environmental [Sensors](https://www.elecfans.com/v/tag/117/) ![pYYBAGOSmm6AJ4PbAAb-7IG-zUo653.jpg](https://file.elecfans.com/web2/M00/82/25/pYYBAGOSmm6AJ4PbAAb-7IG-zUo653.jpg) The BMP180 is the silver square next to the tape on the far left, and the DHT22 is the sensor next to it. There are two environmental sensors on the Urban Garden Monitor, BMP180 and DHT22, which collect data for interpretation by the Arduino 101 and PME. The BMP180 is a barometric pressure and [temperature sensor](https://www.elecfans.com/tags/%E6%B8%A9%E5%BA%A6%E4%BC%A0%E6%84%9F%E5%99%A8/)[that communicates](https://m.elecfans.com/v/tag/1301/) with the device using the [I2C](https://www.elecfans.com/tags/i2c/) bus , while the DHT22 is a temperature and [humidity sensor](https://www.elecfans.com/tags/%E6%B9%BF%E5%BA%A6%E4%BC%A0%E6%84%9F%E5%99%A8/) that communicates with the device using a single digital pin.

If you make a mistake, you can hit the reset button on the monitor and try again. ![poYBAGOW25KAST4BAAAYSPhP5No743.png](https://file.elecfans.com/web2/M00/82/DD/poYBAGOW25KAST4BAAAYSPhP5No743.png) The screen after entering the time. Note that the time should be entered in 24H format. After configuring the time, you should see a menu prompt. Here are the commands you can enter: ![pYYBAGOW25WAKRGrAAA79Uoy9kk356.png](https://file.elecfans.com/web2/M00/83/66/pYYBAGOW25WAKRGrAAA79Uoy9kk356.png) A list of commands printed by the device. - LD: This command creates a 2-second interval loop of sensor data readings using an interrupt service routine. During this time the loop will take precedence over all other commands, so make sure you don't activate any other data display commands during this time or they will be interrupted. This command is recommended when you want to be able to remotely view the environment in which your plants are growing, so you can respond accordingly when conditions change. ![poYBAGOW252AX8T6AACYcM2UZcc383.png](https://file.elecfans.com/web2/M00/82/DD/poYBAGOW252AX8T6AACYcM2UZcc383.png) Internal heat may cause unusually high temperatures. You can subtract offsets to help in your code. - DL: This command closes the ISR data loop. - DD: This command sends a single snapshot of the current sensor data readings. - SS: This command shows the average data and neural network classification for the previous day. If you call this command when no data exists for the previous day, you will be notified and no data will be displayed. - ST: This command displays the data classification for the last 30 days. It will show up as class 0 until the day is classified. Note that class 0 will also be used by the device for the first class. You can modify this by starting the array index at 1 and ending it at 30 instead of 29 if you like. - [DC](https://www.elecfans.com/tags/DC/DC/) : This command displays what each saved numeric day data class represents. If the category has not been assigned a characteristic, the data for all fields will be shown as zero. ![poYBAGOW26CAE6ghAAAiwkLvt88569.png](https://file.elecfans.com/web2/M00/82/DD/poYBAGOW26CAE6ghAAAiwkLvt88569.png) The Display Characterizations command is running. Since the data has not been classified, all values ​​are 0. - SC: This command displays a list of commands, for reference if you need it. ### PME operation When the user operates the board, the Pattern-Matching Engine will run in the background. Every hour, the device records samples of temperature, air pressure, and humidity around the device. This data is then saved to the device as an array. After 24 hours of recording, the device averages each data set and creates a three-variable representation of the past 24-hour environment. This data is then loaded into PME, which classifies it according to the learning experience. If no PME finds a matching previous classification, the data will be assigned a new classification and saved to the PME's memory. Otherwise, assign an existing classification. In both cases, the categories assigned for the day are also saved. Classifications are put into a 30-day array which dynamically fits to prevent overflow, removing the oldest saved dates and shifting all other data up, allowing the most recent [classifications](https://www.elecfans.com/article/zt/) to be recorded. This allows users to see how the environment changes on a daily basis, allowing them to adjust their gardens to potential data increases or decreases. If the number of categories exceeds 30, the oldest category will then be deleted due to the limited amount of storage space in PME. ![poYBAGOW28CAXppwAAaMAbERRn0628.jpg](https://file.elecfans.com/web2/M00/82/DD/poYBAGOW28CAXppwAAaMAbERRn0628.jpg) The Urban Garden Monitor is small enough to fit on the edge of and next to a plant pot. Hopefully this project will give people more time in their lives to give more benefit to the urban gardens they might tend! --- Source: https://maker.wiznet.io/gavinchang/projects/city-garden-monitor/
