They are contained in PubSubClient. h. MQTT_MAX_PACKET_SIZE. Sets the largest packet size, in bytes, the client will handle. Any packet received that exceeds this size will be ignored. Some hardware has a limit to how much data can be passed to them in one go, such as the Arduino Wifi Shield. Default: undefined (complete packet passed in

The measured values are published to a ThingSpeak™ channel. If you have more than one sensor value that you want to send to ThingSpeak, you can choose to publish multiple values to a channel feed. Alternatively, if you have only one sensor, you can publish a single value to a channel field. PubSubClient. h, and DHT. h to your Arduino sketch.
