A suite of open-source sensors and data logger for scientists and engineers
Low cost
Our data logger starts at CAD119 and the Starter kit sells for CAD299.
Ready-to-use
Our Starter Kit comes with the data logger controller, 8 precalibrated temperature sensors and all the accessories. Start collecting data minutes after opening the box.
20+ channels
Measure up to 16 temperatures, 2 digital I2C sensors, 1 0-5V signal, and 1 digital input, all simultaneously.
Open Source
Our firmware, hardware and documents are all open source through a combination of licenses (GNU, MIT, CC).
PC and smartphone compatible
In the field, use a smartphone as a source of power, data storage and visualizer.
Customizable
Adapt the code and the hardware to your specific needs or add functionalities.
High accuracy
Measure temperature with an overall accuracy of +/- 0.5°C.
Auto-sync to cloud
Sync your data in the field through the cellular network.
Open Calibration
Our device is precalibrated at the workshop. Our 3-point calibration procedure can be verified and replicated each year by the user.
Arduino compatible
Based on an Arduino Nano clone, the RDL is programmed and operated like any other Arduino device. This gives you access to the Arduino IDE software and large community of users to help you out.
High acquisition rate
Measure your data up to 300 HZ for 1 channel or up to 1 Hz for 16 channels.
Github based
Find everything you need on our Github repo. Forever. Get updated code, submit bugs, share your design.
Reuse an old phone
Reuse an old smartphone to control the data logger. If you don't need our product anymore, reprogram the Arduino Nano Clone for something completely different.
Designed in Canada
Our products are designed in Montreal, Canada and manufactured in China for affordability.
Graphs
Use your standard spreadsheet program, such as Excel or LibreOffice to convert the text data output into insightful graphs.
Standard features
The RDL comes equipped with a number of features that are ready-tested and ready-to-use.
Temperature
Measure with accuracy up to 16 temperatures between 0 and 100°C with Jericho waterproof thermistors. Measure the temperature of gas, liquid, solids, and surfaces.
Humidity
Measure up to 8 relative humidities using pairs of dry bulbs and wet bulbs, plus 2 humidities with digital i2c sensors.
Illuminance
Measure up to 16 illuminance values with a standard photoresistor probe.
Voltage
Measure one (1) differential voltages between 0 and 5V with the dedicated channel.
Resistance
Measure up to 16 electrical resistances between 100 ohm and 2 MOhms.
Comfort index
Using a low-cost black globe and a wet bulb temperature, let the RDL monitor the comfort with the Wet Bulb Globe Temperature (WBGT) index.
User custom features
With some snippet of Arduino code of your own, you can add custom features to the existent product.
I2C sensors
Integrate your favorite i2C sensor. Choose among hundreds of sensors from stores like Adafruit and Sparkfun. A code example is provided in our source code.
Control signal
Send 0-5V control signals based on your sensor readings. A code example is provided in our source code.
Product limitations
Are there any downsides to our product? One factor that have kept prices up is overengineering.
We focus on “core” functionalities so there are some limitations to our product..
No graphic interface
There is no off-the-box graphic interface for the product, no live graph. Just a live stream of text output. We keep the product simple.
No certification
Jericho and its products have no certification. No CSA, no CE, no A2LA. The trust comes from the high level of transparency inherent to the open source framework, as well as the community of experts that use our product.
Paid user support
We conceived our product as to avoid the need for user support. There is no black box, no proprietary language, nothing kept from the community. Users can solve their problems with the help of the Arduino community and our public documentation. We do however address reported bugs for free.
Not for critical use
This product is not intended for critical applications where the failure or inaccuracy of the device could result in potential harm or financial losses.
