I have ordered one more to go with a wether station a other place. I did that and it worked! Nearly perfect. Opps just learned that this is a digital sensor. I used to think that this was too expensive until I realized how long it makes me to make them myself and now think it is well worth the price. verified purchaser. white to digital pins (tried them all) and a resister soldered between 5v and signal. Helping to ensure more fuel is supplied when the engine is cold or less when the engine is warm. if so, how. After entering my initial (unhappy) review, I read some of the other reviews. Made my own using Sugru to seal the sensor. Temperature plays a vital role in engine performance calculations; a sensor failure can quickly lead to issues such as: black smoke, poor fuel economy, and overheating. It'd be great if it came in different sizes. If you are having trouble, give this orientation a shot. The HOBO MX2201 waterproof temperature logger leverages the power of Bluetooth Low Energy (BLE) to deliver accurate temperature measurements straight to your mobile device with Onset's free HOBOconnect app. The coolant or water temperature sensor T419380 is used to measure the temperature of the engine coolant, which can then be fed back to the ECU, to adjust the fuel ignition and timing. We're seeing accuracies that are more like +/-1.5-3.0 C even in the mid-range of this device. The coolant or water temperature sensor T409471 is used to measure the temperature of the engine coolant, which can then be fed back to the ECU, to adjust the timing and fuel ignition. We wish you a happy, healthy Thanksgiving! This equates to a temperature resolution of 0.5°C, 0.25°C, 0.125°C, or 0.0625°C." There may have been some inconsistencies in the wire colors inside the cable. My sensor shows -2. I just would like an analogic sensor and nothing else. (3) About 1 in every 100 readings, the sensor returns a reading 0-20C off from the actual temperature. I am using this one outside where it is normal with subzero temperatures. All that extra code is well worth it. * Product MX2304 will be added to cart after additional options have been chosen or declined. Water Temperature Transmitters / Sensors; Showing 26 of 26 results GTR101 temperature transmitter replaces Lucas SNB103. Not sure if this is an inconsistency with the manufacturer or if that is the pin out on all of these. It is stable even with a longer cable. and here I have been using these for a while without any decoupling and they work great, the only thing you need is a 4.7k pull up tied between the power and data line. for access to your data in Onset's cloud-based HOBOlink software (indoor deployments). Your cart will be emptied when you change your country. Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. The coolant or water temperature sensor T419414 is used to measure the temperature of the engine coolant, which can then be fed back to the ECU, to adjust the fuel ignition and timing. Black = GND Only 3x4 cm, this tiny data logger measures temperatures over a wide temperature range. If you were going to decouple this, wouldn't you want the capacitor at the DS18B20 end of the thing, instead of 6 feet away? Sparkfun should stock this.. they already stock the pH kit from this company. Most of the time, this sensor returns the correct temperature, but... I was emailed by SFE to write a review on this sensor. Water often needs to be monitored in hard-to-reach locations. I want to bury it 2 meters deep into the ground to measure the temperature near my water pipes - how long can I make the cable without affecting the accuracy of measurements? It shows temperatures that is higher than it really is. The minimum search requirement is the build list, typically 2 to 4 letters followed by 4 or 5 numbers. by Member #1469130 I've used these in my fermentor refrigerator for about a year. Min temperature will be about -15 C, one degree accuracy is fine. At this time, Onset’s ability to build our products and ship them to our customers as scheduled has not been affected by the coronavirus situation. Complete with a precision sensor for ±0.2°C accuracy, this logger measures temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to 50°C (122°F) in water. The TidbiT v2 provides 12-bit resolution and has ±0.2 °C accuracy. The coolant or water temperature sensor T415904 is used to measure the temperature of the engine coolant, which can then be fed back to the ECU, to adjust the fuel ignition and timing. * Product MX2203 will be added to cart after additional options have been chosen or declined. The TMP36 gives me about 0.7v. We just might have to test that out. More or less when it does break down, what is released? Also, does it already have the 4.7k resistor on the data wire? Some kind of epoxy? Doh. Yes it does. I was under the assumption this was decoupled. by Member #353013 These are excellent and reliable. Add the MX Gateway for remote access to your data in Onset's cloud-based HOBOlink software (indoor deployments). +1 on this. Though I would be worried using it with the Discus- they can be real temperamental with 1 Deg F change. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required; or M-RSA pre-assembled Solar Radiation Shield). I would much rather suggest this library as it also supports multiple sensors (and does not try to use some LCD display): https://github.com/milesburton/Arduino-Temperature-Control-Library. can this be interfaced with an arduino pro micro?
