We have data already cleaned and ready to be analysed in R. We need someone to provide graphs from our data. The data contains: temperature, humidity and weight datapoints. Taken every 2 seconds over 12 months. We have this data zipped and ready for R. Already in an R file. We now need someone to work with us to analyse the data . For example: We need to see weight increase and decrease over different time periods. We need to see humidity increase and decrease over different time periods We need temperature increas and decrease over different time periods. Before I send any files , I would like to see if someone can assist with this and what the approximate cost would be. The data we have is not complicated, but it is a lot of data. The analysis we need is also not comp...
Mobile App Development (Native) with MAP and by Integrating Sensor data to routes.
We would like to create a video with 3D animation showing how our liquid metal circuits can replace a rigid circuit board with a super stretchy material that can be embedded into a thin glove, shirt, elbow sleeve, etc. We'd like to show an exploded view of circuit/sensor with the typical "engineering diagram" aesthetic (like in the attachment) pointing out key components and capabilities. Then we would like to animate it “going into” a garment and convey that there is useful data now streaming out of the clothing. Perhaps after the circuit is embedded, we zoom out and see that this garment was being worn by a person and they are performing an action and it is emphasized that the material is still extremely thin and pliable. I have attached some imagery. ...
The project consists of connecting ESP32+RFM95 nodes that have sensors (you don't need to program the sensor, just the communication) to a lora gateway, either multichannel or a packet forwarder (a dual channel gateway). Not necessarily using TTN. The data must be sent to the cloud and the parameters sent by the nodes must be displayed. Proposals are accepted.
a description of the methodology and the required components following a specific format will be provided the work is urgent and needs to be done in 5-6 hours time around 3000 words
I need a base BLE mesh implementation for nRF52 series on a current project. The devices in the mesh network will be 3 or more and will send data to each other. From mobile app i will need to send up to 20 megabytes and receive every seconds sensor data from the BLE devices. Every solution you give will be evaluated first and then implemented. Check documentation:

I need to control the dc motor speed using the Temperature sensor PT 100. The speed of motar should increase /decrease with temperature. The circuit should be simple and cost effective. No need to use microcontroller.
Using foscam cgi to control cameras via scrips in VB so I can run some automation through Homeseer At this stage I can turn off motion sensor - see attached script - But when I run it does enable motion sensor but resets 1) Sensitivity 2) Triger intervals 3) Snap intervals 4) Action - eg send email, push message, take snap shot 5) Schedule 6) Detection area This is the list of scripts from foscam Any help on this would be appreciated
I need an application proof of concept that will allow me to track inventory in different locations in realtime through rfid pasive labels and a sensor. I need help to choose the correct sensor. It should be an entry level sensor around $100 usd and should be able to track up to 100 items in a 1 meter range (or more). The sensor would be connected to an arduino or similar and will write the count of items in a given interval (can be changed via a config file)
We are using Heltec Cubecell HTCC-AB01 1. Code Logic Updates, We like to add some updated logic to our code. 2. Power Loss with Magnetic Reed Switch / Sensor When we connect resistor (10k) and simple magnetic reed switch we are getting major power loss.
Hi, I need someone to make this simple VI for me. I would like to measure the speed of a rotating shaft inside a transmission gearbox. There's 3 shafts in total, each having a hall effect sensor mounted to them. I would like to have the RPM of the shaft displayed on gauges at a rate of 10 Hz minimum (meaning 10 RPM readings per second) in order to have a high speed reading of the speeds. The data must also be logged with their time stamps. Additional info: The speed sensor outputs a voltage (pulse) with each passing gear tooth so you can simulate a high/low digital signal to as an input from the sensor. I have already attempted to write this VI but it is currently unreliable because it fluctuates. The DAQ device I am using is the USB 6002 from NI and I want...
We need a sensor added to a machine that resets a timer each time a knife cuts. The timer needs to be adjustable. Once the timer reaches the limit, the machine needs to shut off. It should be a fairly simple wiring job. This is a one-time job, but if we like your work, we will keep your name on hand for other similar jobs.
We have many simple modules to design like temperature sensor or LED drivers. For each module, you must select the key components and produce schematics and layout in Altium. You must also provide a basic Arduino firmware for basic interactions with the module. The jobs will be awarded on a per module basis but ideally the same person would end up making most of them. You must be experienced with Arduino and Altium.

I have some product development experience and need someone who can integrate these tiny sensors with a low cost microprocessor that will give me the ability to drive 25 simultaneous 3 segment LED digital read outs. The system will have to have dead on accuracy up to .001 (one thousandth of an inch). We may have to consider programming a calibration mode. Each sensor will have a tiny probe above it which will vary by ab...

I need someone to write embedded code in a Microchip PIC16F15243. The design includes a MEMS accelerometer and magnetometer that communicates with the uC vis I2C. The uC will need to process the signals from the accelerometer and magnetometer. The processing is relatively simple, a threshold above the baseline level. The device will operate on AA batteries so the uC and sensors will need to go in and out of sleep mode.
Hi, we wish to develop a Desktop software based on Xojo for our Data Logger product. This will give input in Modbus RTU to the PC and data has to be stored for all channels, alerts, alarms, digital inputs etc. An Excel/CSV file will have to be generated for the temperature based on date range, or alerts that have happened. If user has knowledge of CFR-21 compliance it would make the project much easier.
...sound commentary would give the feeling of a game such as “New High Score”, “You’re Slowing Down”, “Congratulations!” Multiple pressure sensors can be used for a single target to detect accuracy. By hitting the center sensor for example would give a 100% accuracy hit but by hitting a surrounding sensor may indicate a 75% accuracy. A similar commercial product used for reaction training can be seen here from to give you an idea of what it could look and feel like. It’s possible to turn an MMA/boxing punch bag into a game by strategically placing multiple sensor/pressure pads aligned inside of the bag to use as hit targets. Sensors would be placed around the bag in areas representing targets such as the head and body...

Low cost wireless thermometer that is available on the local network and has very simple API. Once go the the thermometer address in the browser it should return json data containing temperature and the battery procent. This should be built very power efficient, i also want the batteries to be exchangeable and i should be able to charge the device, for example 2x21700 or 18650 batteries. Also the smaller size, the better. I want to receive full working device. I am satisfied with the device, i would like to start massive production.
