Load Cells, HX711, Negative Reading...Now What? : Esphome


ksheyman. · 6m · edited 6m. It doesn''t really matter that the values are negative. Just use a calibrate linear filter. Once attached to the bed, set 0 as the value when the bed is empty, and then set like 100 to the value when the bed is occupied. Now you have a positive, meaningful value. Edit: also curious what kind of load cells you''re using.

IAQ (Indoor Air Quality) Board — ESPHome


IAQ Board is a DIY device for measuring internal air quality running with esphome. It’s quite small and is based on a custom PCB where part of the components are soldered and connected. Here is what it can measure: Temperature / Humidity / Pressure. Air particles PM1, , PM10. Carbon Dioxide with NDIR sensor

Build a cheap air quality sensor using ESPhome, Home ...


Feb 03, 2021· The air quality sensor. To measure the air quality, we’re using a PMS5003 Particulate Matter Sensor. This sensor measures Particulate Matter concentration of three size of particles <µm, <µm and <µm concentrations. The PMS5003 sensor uses laser technology to measure the concentration of particulate matter in the air.

T6613/15 CO2 Sensors — ESPHome


T6613/15 CO2 Sensors. ¶. The t6615 sensor platform allows you to use T6613 and T6615 family sensors ( amphenol) with ESPHome. T6613 sensors are unreferenced and require ABC to calibrate daily, while the T6615 sensors have a sealed reference gas and do not require ABC calibration. All ppm ranges are supported by this platform.

Apr 01, 2021· Apr 01, 2021· Surely you know that carbon monoxide is a tasteless, odorless, and poisonous gas that occurs as a combustion byproduct. If you have any gas appliances in your home, such as an oven, water heater, furnace, and fireplace, you should have a CO detector installed.

Tindie Blog | A CO2 Sensor for ESPHome


Aug 13, 2020· A CO2 Sensor for ESPHome. With so many people spending so much time indoors lately, Greg from Greg’s Tinker Town wanted to develop a board that could interface an ESP32 to an MHZ19B CO2 sensor – and so that’s exactly what he did! The MHZ19B is a pretty neat sensor. It uses nondispersive infrared to detect the concentration of CO2 in ...

nodered – Internet of Things projects


Dec 03, 2019· Following the ESPHome introduction, we use the Winsen CO2 sensor to measure indoor CO2 level. For reference look at the datasheet. The sensor outputs the measured CO2 level in a PWM signal and a UART (serial) stream. We will use the UART interface in our example. Connection. We need four connections: power (5V – 150mA, GND, Rx and Tx).
