Soil ph sensorJobs

I need to have the ultrasonic mister to work. I have coupled with an arduino nano board on the 5v pin. Its not working. Later i will need to add a pir sensor.

We want to create an automatic technical service report for our service engineers to use and to be given to a customer instantly on site. The report would spit out actions for the customer depending on the results which are populated into the report. The data input would have upper and lower limits such as pH reading to which responses will be generated if the results are outside these limits etc. There is a few different test methods which would require specific routes & actions if they are within or out of specification.

Do you know what happens to your plastic pen after it is used? Recycled? NO! More than 60 billion disposable plastic pens are used & thrown every year & they are not recycled! These pens end up in landfills, incinerators, or water bodies–polluting our air, water & soil systems. At PenPals, we have designed 3-tier solution for this issue – REDUCE, REUSE & UPCYCLE. PenPals spreads awareness to REDUCE use of disposable pens - Collects & segregates used pens at source where refillable pens are refilled & put to REUSE & non-refillable pens go for UPCYCLING. PenPals is world's 1st initiative to have designed widest range utility products made by upcycling waste pens. BIC, world’s leading pen manufacturing company, in 2005 sold their 100-...

Need a very informal liquefaction assessment which only requires reporting the findings of the soil in a 3 foot deep hole and referencing previous reports with a hold harmless clause. Examples attached.

...rider will approach a stop sign. The rider must come to a complete stop to ensure they are all starting at the same location and not getting any unfair advantage. To control riders approaching the stop sign, we are creating a physical ‘control gate’ which is a physical rod (like wooden dowel) attached to a servo motor. On this rod, we would like to mount the sonar sensor so we know when a rider is approaching. The sonar sensor would detect a rider who is 100cm away. We then wait for 5 seconds to ensure the rider has come to a complete stop. Then the gate will swing open 90 degrees and stay open for 5 seconds so we know the rider has departed and then the gate will return to close (0 degrees) Then a timer starts. After 10 seconds, a row on the LED matrix wi...

...instructional and content designers will vividly demonstrate why and how the students project worked. Our hardware and software will interact with the Cloud in real time. We will demonstrate for them, exactly what happens when they set up an object on their project and how it uses the cloud to communicate with a sensor and how all the activities can have the desired outcome like turning lights on and off in a remote location. Although the engineering that goes into making a sensor, building a Cloud environment and writing sophisticated, IF - THEN - ELSE statements can be complicated, this is NOT what we want to teach students. We simply want to introduce them to the concepts. Once students are familiar with concepts, we can gradually introduce them to more sophisticate...

...glove, in which I have a MAX30102 sensor (heart rate, SpO2, temperature sensor) connected to an Arduino. The MAX30102 is placed on the tip of the index finger; please see the attached photo for demonstration. For reading the MAX30102 data, I used the following algorithm from GitHub: . For further explanation of the algorithm see the following link: However, this algorithm sometimes does not give accurate readings on different skin colors and does not consider the effects of motion artifacts. Therefore, I want you to write an Arduino code that includes an algorithm to accurately detect heart rate, SpO2, and temperature using the MAX30102 sensor and to cancel motion artifacts

I am making an escape room prop where I am using a python/flask script to run an Adafruit ToF laser sensor to act as a theremin to make tones in a game. That part of the project is working fine. The problem is between flask and the front end. I need it to communicate to front end and update the notes being sent (or other logic). It was rendering the template sometimes but now it is not doing it at all. I get "This site can't be reached" refused to connect, ERR_CONNECTION_REFUSED. There is no firewall. It started when I added a setInterval() in javascript - but now even when I have removed that code, I still get the problem. So I would like help to remove this problem first and then to connect flask to the front end where I can pass info back and forth. I w...

Only contact us if you are in possession of a HackRF or any other RTL-SDR device. We are in the need to capture the identifiers (packets) from vehicle's Tire Pressure Monitoring Systems (TPMS). Each latest device with a TPMS transmits every x-time a packet - we need to capture this. The data transmitted consists primarily of a sensor ID, the tyre pressure, the tyre temperature and a checksum (other status bits are also transmitted). The software must be developed for a specific Ubuntu version and operational on Raspberry Pi. Budget $500 We prefer if you already have experience with this.
