Temperature Sensor Using NTC Thermistor (Arduino/NTC)
A thermistor (THERMally sensitive resISTOR) is an electrical resistance whose value changes with the temperature. Thermistors are divided into two groups, hot conductors which have a negative temperature coefficient (NTC), conduct electrically in a hot state better than in the cold state and cold conductors, which have a positive temperature coefficient (PTC) and conduct better electrically when … [Read more...]
IoT Based Pulse Oximeter With ESP32, MAX30102 and IBM Watson IoT
Pulse oximeters are in use since long during an operation, in intensive care, in the emergency room and other places such as in unpressurized aircraft. The COVID-19 pandemic made pulse oximetry technology for the consumers. Most of the finger pulse oximeters in the market lack BLE and Wi-Fi. There are only a few finger pulse oximeters which have a BLE to transmit data to the smartphone. Having a … [Read more...]
