How much water do you drink a day You will be aware of the importance of The habit of drinking water without mentioning. We need to drink more water. So, I wanted to know how much drinking water. #### Components WIZwiki W7500(Wiznet) ?? 2 Xbee(Digi) ?????????? 2 SD card ???????????? 1 OLED Display(SeeedStudio) ?? 1 Load Cell + HX711 ?????? 1 LED ????????????? 2 Tact Switch ????????? 2 #### Overall Scheme ![](https://hackster.imgix.net/uploads/image/file/78705/0_all.png?auto=compress%2Cformat&w=740&h=555&fit=max) When I drink water, a Client send amount of water to Host. Host can store the amount of water and Real time(using NTP) to SD card. #### How to check the amount of water you drink. 1. Make a chart and tick it off each time you drink a glass. 2. Automatic sensing - Ultrasonic sensor to check the amount of water - Measure weight of the water. ##### Weight of water? Pure water has its highest density of 1000 kg/m3 at temperature 4C(39.2F) - 1g = 1ml #### Load cell + HX711 ##### Strain gauge The force being sensed deforms a strain gauge. The strain gauge measures the deformation (strain) as a change in electrical resistance, which is a measure of the strain and hence the applied forces. ![](https://hackster.imgix.net/uploads/image/file/78706/2_loadcell.png?auto=compress%2Cformat&w=740&h=555&fit=max) ##### Make Cup holder(3D modeling) ![](https://hackster.imgix.net/uploads/image/file/78707/3_loadcell.png?auto=compress%2Cformat&w=740&h=555&fit=max) used 123D Design tool ##### Calibration & Measurement ![](https://hackster.imgix.net/uploads/image/file/78708/4_calibnmeasure.png?auto=compress%2Cformat&w=740&h=555&fit=max) This 9V battery is 44g and I made sure that the measurements. (W:43g -> Current weight, B:43g -> Temporary value for comparison) For Calibration, You have to change the value of scale in source code. #### Hardware ##### Client ![](https://hackster.imgix.net/uploads/image/file/78709/5_client.png?auto=compress%2Cformat&w=740&h=555&fit=max) ##### Host ![](https://hackster.imgix.net/uploads/image/file/78710/6_host.png?auto=compress%2Cformat&w=740&h=555&fit=max) ##### Overall ![](https://hackster.imgix.net/uploads/image/file/78711/7_total.png?auto=compress%2Cformat&w=740&h=555&fit=max) #### Operation method ##### Test data ![](https://hackster.imgix.net/uploads/image/file/78712/8_flow.png?auto=compress%2Cformat&w=740&h=555&fit=max) 1. Client send the data to Host. send 134: data type(Store at SD card: 1) + amount of water(34ml) 2. Access and request to NTP server for realtime. 3. Save realtime and a amount of water in SD card. ##### Actual data ![](https://hackster.imgix.net/uploads/image/file/78713/9_flow1.png?auto=compress%2Cformat&w=740&h=555&fit=max) 1. Put up a cup of water on top of the Load cell weight sensor 2. Client sensed 264ml of water. 3. When I was drinking water, W:0(Current weight:0, because of holding the hand), B:264(saved weight:264) 4. Sensed 180ml. 5. Put up a cup of water again. send data type(1) + 84ml of water. #### Logged data on SD card ![](https://hackster.imgix.net/uploads/image/file/78714/10_waterlog1.png?auto=compress%2Cformat&w=740&h=555&fit=max) #### Visualization But, you don’t have to think about is do a few liters of water a day You just have to set the target amount of water. Then you can see the percentage of data like below. #### Source code repository in mbed ##### Client ##### Host --- Source: https://maker.wiznet.io/annjaison/projects/Easy-way-to-drink-more-water-every-day-IoT-Project/
